5 Steps On How To Become An International Lawyer

To become an international lawyer, you complete 5 steps: earn a bachelor’s degree, take the LSAT, enroll in law school, take and pass the bar exam, and consider an LL.M in international law. An international lawyer, also called an international law attorney, advises governments, companies, organizations, and individuals on legal matters that cross national borders, from treaties and trade to cross-border deals and disputes. The full path takes about 7 years of study plus bar admission, and it rewards strong research, languages, and cultural fluency.

International lawyers work where legal systems meet. They negotiate cross-border contracts, argue before international tribunals, advise on treaties and sanctions, and help clients operate across the 193 member states of the United Nations and beyond.

This guide explains how to become an international lawyer in 5 steps. It then defines international law and the international lawyer’s role, lists the fields these lawyers practice, weighs the advantages and disadvantages, and covers timeline, majors, salary, demand, and notable figures. For the profession in general, see our overview of how to become a lawyer and our directory of lawyer types.

The table below summarizes the 5 steps and the stage each one belongs to, before the sections that follow explain every step in detail.

StepWhat it involvesTypical duration

4. Take and pass the bar examState licensing exam plus character and fitness review2-3 months of preparation plus admission
5. Think about pursuing an LL.MOptional 1-year specialization in international law1 year full time

Each step builds on the ones before it. The first four steps are the same license-track ladder every US lawyer climbs; the fifth step, along with the courses, clinics, and languages you choose inside the earlier steps, is what turns a licensed attorney into an international lawyer.

1. Obtain a Bachelor’s Degree

The first step to becoming an international lawyer is obtaining a four-year bachelor’s degree, which every American Bar Association accredited law school requires for admission. No specific major is required, but international relations, political science, economics, history, and foreign languages build the reading, writing, and cross-cultural skills international practice demands.

Law schools in the United States admit students only after a completed bachelor’s degree. This makes the undergraduate degree the non-negotiable foundation of the path, whatever field you study.

The bachelor’s degree matters for 3 reasons. First, your grade point average is one of the two numbers law schools weigh most heavily in admissions. Second, your coursework is your first chance to build international context, through classes in comparative politics, world history, trade, and diplomacy. Third, your undergraduate years are the cheapest time to reach professional fluency in a second language, an asset international employers screen for.

Use these years deliberately. Take writing-intensive seminars, because international practice runs on memos, briefs, and treaty analysis. Study abroad if you can, because time inside another legal culture is evidence of the adaptability the field requires. Join Model United Nations, moot court, or debate to practice structured argument early. A structured pre-law track can organize all of this, but it is optional; admissions committees care about grades, rigor, and evidence of sustained interest more than any specific major label.

Aim for a GPA of 3.5 or higher if you want realistic access to law schools with deep international programs. Grades compound from the first semester, so treat freshman year as part of your law-school application, not a warm-up.

2. Take the LSAT

The second step to becoming an international lawyer is taking the LSAT, the standardized admission test most US law schools use to compare applicants. The exam tests reading comprehension and logical reasoning, and your score, together with your GPA, largely determines which law schools admit you and what scholarships they offer.

The LSAT is scored on a 120-180 scale. Schools with strong international-law programs tend to sit in the more competitive bands, so a score in the 160s or higher opens the widest set of doors. Our guide to LSAT scores breaks down what different bands mean for admissions.

Plan 3-6 months of preparation. Build your study plan around full timed practice tests, then drill the question types that cost you points. Our guides on how to prepare for the LSAT and when to take the LSAT cover schedules, materials, and test-day logistics in detail.

Take the exam by the summer or early fall of the year before you plan to enroll. Retaking is allowed and common if your first score undershoots your practice average, and most schools consider your highest score. The LSAT hub collects everything from registration costs to retake strategy in one place.

The LSAT has no international-law content. Its value for a future international lawyer is indirect but real: the reading sections train you to pull precise meaning out of dense text, which is the daily work of treaty and contract interpretation.

3. Enroll in Law School

The third step to becoming an international lawyer is enrolling in an ABA-accredited law school and earning a Juris Doctor, a three-year degree that qualifies you to sit for the bar exam. Choose a school with international-law courses, clinics, journals, and study-abroad exchanges, then build your 2L and 3L schedule around them.

The Juris Doctor is the professional law degree in the United States. The first year covers the fixed core: contracts, torts, civil procedure, property, criminal law, and constitutional law. International specialization happens in years two and three, when you control your schedule.

Build that schedule around 5 course groups: public international law, international business transactions, international trade and investment, conflict of laws, and international arbitration or litigation. Add a clinic or externship with a cross-border docket, write for an international-law journal, and compete in the Jessup or Vis moots if your school fields teams. These credentials are what international employers actually read on a resume.

School choice shapes access to all of this. Compare programs through our law school hub, our guide to the best international law schools, and the national law school rankings. State-level hubs help you weigh regional options and in-state costs; the Top Law Schools in Oklahoma page is one example of how to evaluate a state market school by school.

Cost discipline matters as much as prestige. International practice concentrates in large firms, government, and organizations with long hiring pipelines, so graduating with manageable debt keeps lower-paying but career-defining options, like a State Department honors program or a tribunal clerkship, financially possible.

4. Take and Pass the Bar Exam

The fourth step to becoming an international lawyer is taking and passing the bar exam in the state where you intend to practice, because international law is practiced through a domestic law license. Most states use the Uniform Bar Examination, and every state adds a character and fitness review before admission.

There is no separate “international bar.” A US-trained international lawyer is licensed by a state, then applies that license to cross-border work. Start with our bar exam hub and the state-by-state bar exam requirements guide when choosing where to sit.

The Uniform Bar Examination combines the Multistate Essay Examination, two Multistate Performance Test tasks, and the Multistate Bar Examination, and it produces a portable score on a 400-point scale that transfers between UBE jurisdictions. Portability is valuable for internationally minded lawyers because careers in this field move between New York, Washington DC, and other hubs; our guide to bar reciprocity explains how transferred scores and admission on motion work.

The exam itself is changing. The National Conference of Bar Examiners administers the NextGen UBE in a first group of jurisdictions starting July 2026, and the current MBE, MEE, and MPT run through the February 2028 exam before full replacement in July 2028. Check which version your target state administers before you build a study calendar.

New York deserves a specific mention. It is the busiest US market for cross-border work, and it permits certain foreign-trained lawyers to qualify for its bar after an American LL.M, which is why the New York exam has become a global credential in its own right.

5. Think about pursuing an LL.M

The fifth step to becoming an international lawyer is deciding whether to pursue an LL.M, an optional one-year Master of Laws that deepens specialization in fields like international trade, arbitration, or human rights. An LL.M is not required to practice, but it sharpens credentials for tribunal, academic, and specialized-practice roles.

The Master of Laws (LL.M) is a post-JD degree completed in about one year of full-time study. For international careers it serves 3 purposes: focused coursework in a niche such as investment arbitration or the law of armed conflict, a second alumni network in another city or country, and a signal of commitment that matters in competitive hiring pools at international organizations.

An LL.M abroad has extra value in this field. A year at a European, Asian, or Latin American faculty gives you working exposure to a civil-law system, which most US JDs never study, and civil-law fluency is a genuine differentiator in treaty work and cross-border disputes.

Weigh the cost honestly. Tuition for a year can rival a year of law school, and large-firm hiring in the United States runs through the JD, not the LL.M. Our comparison of the LL.M vs JD explains which degree does what, and for whom the LL.M actually changes outcomes.

Skip it without guilt if your target is transactional practice at a US firm; take it seriously if you aim at international tribunals, foreign ministries, academia, or a specialized bar like international tax or trade remedies.

What is an International Law?

International law is the body of rules, treaties, and customs that defines the legal responsibilities of states in their conduct with each other and in their treatment of individuals within state boundaries. It governs human rights, trade, the use of force, the seas, diplomacy, and the global commons.

The United Nations describes the domain of international law as covering human rights, disarmament, international crime, refugees, migration, nationality, the treatment of prisoners, the use of force, and the conduct of war, along with global commons such as the environment, international waters, outer space, global communications, and world trade. More than 560 major multilateral treaties are deposited with the UN Secretary-General, and the International Law Commission, a body of 34 experts, works to codify and develop the field.

International law has 2 main branches. Public international law governs relations between states and international organizations: treaties, statehood, state responsibility, the law of the sea, and international humanitarian law. Private international law, also called conflict of laws, decides which country’s law applies to cross-border disputes between private parties and how foreign judgments are recognized.

Courts and tribunals give the field teeth. The International Court of Justice, the principal judicial organ of the United Nations, sits at the Peace Palace in The Hague with 15 judges elected to nine-year terms, and it has considered more than 200 cases between states since 1946. The International Criminal Court, created by the Rome Statute that 120 states adopted in 1998, prosecutes individuals for genocide, crimes against humanity, war crimes, and the crime of aggression.

For the doctrine in depth, including sources, treaties, and enforcement, read our full guide to International Law: Exploring Global Legal Principles and Treaties. This page stays focused on the career built on that doctrine.

What is an International Lawyer?

An international lawyer is an attorney who advises and represents clients on legal matters that cross national borders or arise under international law. The role, also called an international law attorney, spans treaty work for governments, cross-border deals for companies, and disputes before international courts and arbitral tribunals.

The expanded definition has 3 parts. First, an international lawyer holds a domestic law license, usually from a US state or a foreign bar, because no worldwide license exists. Second, the lawyer’s subject matter involves more than one legal system: a treaty, a foreign investment, a cross-border contract, a sanctions regime, or a dispute between parties in different countries. Third, the lawyer’s toolkit combines domestic law with public or private international law.

An international law attorney works in 4 main settings. They are large law firms with global offices, government departments such as a foreign ministry or trade agency, international organizations such as the United Nations and its tribunals, and non-governmental organizations focused on human rights or development. A smaller number teach and write as academics, shaping the doctrine itself.

The label describes a practice orientation rather than a single job. A trade lawyer in Washington, an arbitration counsel in New York, a legal adviser at a foreign ministry, and a prosecutor at an international tribunal are all international lawyers, even though their daily work differs sharply.

What does International Lawyer do?

An international lawyer researches foreign and international law, drafts and negotiates cross-border contracts and treaties, advises on compliance with sanctions and trade rules, and represents clients in international litigation and arbitration. The daily work mixes writing, negotiation, and coordination across time zones and legal systems.

A typical week includes 5 kinds of tasks. They are legal research across multiple jurisdictions, drafting agreements and memoranda, negotiating with counterparties or foreign counsel, managing disputes before courts or arbitral tribunals, and advising clients on regulatory exposure such as export controls, sanctions, and anti-corruption rules.

The forum depends on the client. States litigate before the International Court of Justice, which hears contentious cases between states and issues advisory opinions to UN organs. Companies more often arbitrate, because arbitration awards travel across borders more easily than court judgments. Individuals accused of the gravest crimes face the International Criminal Court, where 18 judges sit in pre-trial, trial, and appeals divisions.

Coordination is the underrated half of the job. An international lawyer rarely knows every relevant legal system, so a large part of the work is instructing and synthesizing advice from local counsel in other countries, then translating it into a single coherent recommendation the client can act on.

What type of Laws do International Lawyers practice?

International lawyers practice public international law, international trade law, international arbitration, international corporate and investment law, immigration law, international human rights law, international criminal law, maritime law, and international tax and competition law. Most build a career in 1 or 2 of these fields rather than all of them.

The main practice fields are the following:

  • Public international law: treaties, statehood, boundaries, and state responsibility, practiced mainly for governments and international organizations.
  • International trade law: tariffs, trade remedies, export controls, and World Trade Organization disputes.
  • International arbitration: commercial and investor-state disputes resolved outside national courts.
  • International corporate law: cross-border mergers, joint ventures, and foreign investment structuring.
  • Immigration law: visas, asylum, and citizenship questions that move people across borders.
  • International human rights law: claims under human rights treaties before regional courts and UN bodies; see our guides to human rights law and the human rights lawyer career.
  • International criminal law: prosecution and defense of genocide, war crimes, and crimes against humanity.
  • Maritime and law of the sea: shipping, boundaries, and ocean resources; see our maritime law guide.
  • International tax and competition: cross-border tax structuring and multi-jurisdiction merger and antitrust review; see competition law.

The fields reward different temperaments. Trade and tax reward technical, regulation-heavy minds; arbitration rewards advocates; human rights and criminal work reward stamina and fieldwork tolerance; corporate work rewards deal-makers who can close across cultures.

Can International Lawyer practive Immigration Law?

Yes, an international lawyer can practice immigration law, and many do, because immigration sits at the intersection of domestic statutes and international movement of people. US immigration practice requires a US law license, and any licensed attorney can add immigration to an international practice.

Immigration is domestic law with an international client base. The statutes are national, but every case involves a foreign national, foreign documents, and often treaty questions such as refugee protection. That overlap makes immigration a natural entry point into cross-border work and a common sideline for corporate international lawyers who handle work visas for client employees.

The two careers still differ in center of gravity. A dedicated immigration practice is high-volume and procedure-driven, while a general international practice is deal- or dispute-driven. Read our doctrine guide to Immigration Law: Exploring Legal Principles for Migration and Citizenship and our companion page on the immigration lawyer career to compare the tracks.

Do International Lawyers handles International Corporate Law?

Yes, international lawyers handle international corporate law, and it is the largest source of private-sector work in the field. Cross-border mergers, joint ventures, financing, and foreign direct investment all require counsel who can align company law, contracts, and regulation across 2 or more countries.

International corporate law is where most international lawyers in law firms actually spend their hours. A single cross-border acquisition raises corporate approvals in one country, merger control in several, foreign-investment screening in another, and a governing-law and dispute-resolution choice that ties it together. The international lawyer quarterbacks that structure with local counsel executing each national piece.

The skill base is corporate first, international second. Master the deal mechanics in our guide to Corporate Law: Navigating Legal Principles and Business Regulations, then layer the cross-border elements on top; the corporate lawyer career page shows how the domestic track compares.

Why become an International Lawyer?

Become an international lawyer for work that combines intellectual depth with global consequence: shaping treaties, resolving disputes between states and multinationals, and protecting rights across borders. The field offers strong pay in private practice, mission-driven roles in public service, and a career that travels.

The reasons fall into 4 groups. First, the subject matter is consequential: sanctions, trade wars, territorial disputes, and human rights claims are front-page issues, and international lawyers work on them directly. Second, the variety is unmatched, because every matter introduces a new legal system, industry, or region. Third, the career is portable across employers and continents in a way few legal specialties are. Fourth, the field’s private-practice segment pays at the top of the profession.

There is also a values case. International law is the main peaceful machinery for settling disputes between states; lawyers who master it expand the space where argument replaces force. For many practitioners that purpose, more than pay, is the reason they stay.

What are the advantages of becoming an International Lawyer?

The advantages of becoming an international lawyer are high earning potential in global firms, intellectually demanding and varied work, international travel and mobility, access to prestigious institutions, strong demand for cross-border skills, and the chance to work on matters of global consequence.

The 6 main advantages are the following:

  • High earning potential: large-firm cross-border practice sits at the top of the salary market, well above the all-lawyer median of $151,160 reported by the Bureau of Labor Statistics for May 2024.
  • Varied, demanding work: each matter brings a new jurisdiction, industry, or treaty regime, so the learning curve never flattens.
  • Travel and mobility: hearings, closings, and secondments move you between financial and diplomatic capitals.
  • Prestige and institutions: the field’s arenas include the ICJ, the ICC, arbitral institutions, and foreign ministries.
  • Durable demand: globalized commerce, sanctions, and supply-chain regulation keep generating cross-border legal questions.
  • Global impact: the work shapes treaties, trade flows, and rights protections that reach far beyond one client.

The advantages compound with languages. A practitioner fluent in Spanish, Mandarin, French, or Arabic can serve client regions that English-only competitors cannot, which shows up directly in staffing and promotion decisions.

What are the disadvantages of being an International Lawyer?

The disadvantages of being an international lawyer are long and irregular hours across time zones, heavy travel that strains personal life, intense competition for a small number of true international roles, lower pay in public-interest and tribunal positions, and constant pressure to keep up with fast-changing regulation.

The 5 main disadvantages are the following:

  • Time-zone hours: calls with Asia at night and Europe at dawn stretch the workday beyond the usual firm schedule.
  • Travel fatigue: frequent trips sound glamorous and wear thin quickly, especially for lawyers with families.
  • Scarce seats: genuinely international roles at tribunals, organizations, and elite practice groups attract global applicant pools far larger than the openings.
  • Pay spread: NGO, tribunal, and academic roles pay a fraction of large-firm rates, so mission-driven paths demand financial planning.
  • Regulatory churn: sanctions lists, trade rules, and investment-screening regimes change monthly, and clients expect same-day fluency.

The honest summary: the field trades comfort for range. Lawyers who need predictable hours and a fixed body of law are happier in domestic practice; lawyers energized by movement and novelty absorb the costs willingly.

How long does it take to become an International Lawyer?

It takes about 7 years of full-time study to become an international lawyer: 4 years for a bachelor’s degree and 3 years for a Juris Doctor, followed by 2-3 months of bar preparation and admission. An optional LL.M adds 1 year, and specialized credibility in the field typically takes 3-5 more years of practice.

The 7-year figure is the license track, not the finish line. International groups at large firms treat the first years of practice as training in a base discipline such as corporate, disputes, or trade; a lawyer usually earns the “international” label through matters handled between roughly years 2 and 7 of practice.

Four factors make the path longer than usual. Part-time or evening JD programs stretch law school to 4 years. Gap years between degrees, common for work or fellowships, add time but often strengthen applications. A failed first bar attempt adds 6 months to a year. An LL.M, a judicial clerkship, or a tribunal traineeship each adds a year, though all three raise the ceiling of the career they delay.

Two factors shorten the effective timeline. Summer positions in international practice groups convert directly into offers, collapsing the job search. Language skills acquired before law school remove the single slowest credential to build later, because professional fluency cannot be crammed the way a course can.

Foreign-trained lawyers follow a compressed variant of this path. An attorney already licensed abroad can complete a one-year American LL.M and, in states such as New York, qualify to sit for the bar without a US JD, cutting the American leg of the journey to roughly 18 months from enrollment to admission.

Plan the sequence backward from a target role. Tribunal and organization posts hire on cycles with hard application windows, government honors programs recruit in the fall of 3L year, and firm offers flow from the 2L summer. Mapping those dates in year one of law school prevents the common mistake of discovering a deadline one year after it mattered.

What is the best major for International Law?

The best major for international law is international relations, followed by political science, economics, history, and a foreign language. Law schools accept every major, so the best international lawyer course of study is the one that builds strong writing, global context, and a high GPA at the same time.

The 5 strongest majors are the following. International relations teaches the state system, treaties, and organizations the field runs on. Political science builds institutional and comparative context. Economics underpins trade, investment, and sanctions work. History trains archival research and long-form writing. A foreign-language major delivers the credential employers can verify in an interview.

Pair the major with a deliberate minor. An international-relations major with an economics or language minor covers more of the field’s demands than any single program. Students planning a technical practice such as international tax can substitute accounting or finance without penalty.

No undergraduate international lawyer course is mandatory, and admissions committees say so consistently. A 3.9 GPA in philosophy beats a 3.2 in international relations, because the JD, not the bachelor’s degree, supplies the legal content.

Is International Law hard law?

Partly, yes: international law contains both hard law and soft law. Treaties, conventions, and binding court judgments are hard law that obligates the states bound by them, while declarations, guidelines, and resolutions are soft law that persuades without binding. Enforcement is the field’s weak point, not validity.

The hard core is real. A ratified treaty binds its parties, ICJ judgments are final and without appeal between the litigating states, and domestic courts enforce many international obligations directly. The doubt people voice about international law concerns enforcement: no world police compels a losing state to comply, and compliance ultimately runs through political pressure, reciprocity, and the UN Security Council.

The question also carries a second meaning: is international law hard to study? It is demanding rather than hard in the mathematical sense. The sources are scattered across treaties, custom, and case law in multiple languages, and the analysis requires holding several legal systems in mind at once. Students who like structure over memorization tend to do well.

Do International Lawyers travel frequently?

Yes, international lawyers travel frequently compared with domestic practitioners, though less than the image suggests. Arbitration counsel travel for hearings, deal lawyers for closings and negotiations, and tribunal and NGO lawyers for fieldwork, while much routine cross-border work now runs through video calls.

Travel load varies by role. Disputes lawyers cluster trips around hearing weeks in arbitral seats such as Paris, London, Geneva, and Singapore. Transactional lawyers travel for signings and key negotiations. Human rights and international criminal lawyers log the hardest travel, into post-conflict regions for interviews and evidence.

The trend line points down, not up. Video conferencing since 2020 moved procedural hearings, due diligence, and most client meetings online, so mid-career international lawyers today travel meaningfully less than the prior generation while covering more jurisdictions. Expect bursts of intense travel around case milestones rather than a constant suitcase life.

Does International Lawyer work internationally?

Yes, an international lawyer works internationally in subject matter, and often in location. The work always spans multiple countries’ laws, and many practitioners take postings abroad through firm offices, secondments, foreign ministries, or international organizations, while remaining licensed by their home bar.

The license stays domestic while the work goes global. A New York-admitted lawyer in a firm’s London or Singapore office practices US law and international matters from abroad, usually registered locally as a foreign legal consultant rather than admitted to the host bar. Common abroad-tracks include firm office rotations, client secondments, embassy and ministry legal posts, and staff positions at organizations such as the UN or the World Trade Organization.

Plenty of international lawyers never relocate. A trade lawyer in Washington or an arbitration specialist in New York can spend an entire career on international matters from one city. Working internationally describes the docket first; the passport stamps are optional.

How much does International Lawyer make?

International lawyers make between roughly $73,000 and well over $239,200 per year depending on setting, against a median of $151,160 for all US lawyers reported by the Bureau of Labor Statistics for May 2024. Large-firm cross-border practice pays above the median; NGO and tribunal roles pay below it.

So do international lawyers pay well? In private practice, yes: cross-border corporate, arbitration, and trade groups sit inside the large-firm salary market, whose senior lawyers populate the top decile above $239,200. Public-service pay is more modest but concrete; a Member of the International Court of Justice, the pinnacle of the public field, receives a 2026 annual base salary of US$212,784 plus post adjustment, with a US$25,000 supplement for the Court’s President.

The table below shows how setting drives pay across the field.

Practice settingTypical pay positionNotes
Global law firm (corporate, arbitration, trade)Above the $151,160 all-lawyer median; senior lawyers in the top decile above $239,200Highest pay; longest hours
US government (State, Commerce, USTR)Federal attorney pay scales; below large firmsStrong training and exit options
International organizations and tribunalsStructured UN-style scales; ICJ judges earn a $212,784 base in 2026Tax treatment often favorable
NGOs and human rights groupsBelow the all-lawyer median, often near the bottom decile early onMission-driven; grant funded
AcademiaVaries by school; supplemented by arbitration appointmentsSenior scholars sit as arbitrators

Specialty moves the number as much as setting does. Investor-state arbitration and international tax command premium billing rates, and on average compensation for international arbitration partners illustrates how far the top of the market runs above the profession-wide median.

Early-career pay follows the base discipline. A first-year associate in an international group earns the same lockstep salary as domestic peers at the firm; the international premium arrives later, through rate, book, and mobility rather than a different starting number.

How common International Lawyers are?

International lawyers are uncommon relative to the profession: they are a small specialty concentrated in global cities, government, and international institutions, within a US profession of roughly 1.3 million licensed attorneys. Demand for cross-border skills is nonetheless steady and growing as trade, sanctions, and data rules multiply.

The concentration is geographic and institutional. US international practice clusters in New York and Washington DC, with secondary hubs in Houston, Miami, San Francisco, and Los Angeles. Globally the field gathers where its institutions sit: The Hague for courts and tribunals, Geneva for trade and human rights bodies, and London, Paris, and Singapore for arbitration.

Are international lawyers in demand? Yes, and the demand is regulation-driven. Sanctions programs, export controls, foreign-investment screening, cross-border data rules, and supply-chain due diligence statutes have all expanded since 2020, and each expansion creates compliance work that only lawyers comfortable across borders can do. The Bureau of Labor Statistics projects 4 percent employment growth for lawyers overall from 2024 to 2034, with about 31,500 openings per year, and cross-border regulatory work is one of the segments adding questions faster than average.

Professional infrastructure marks the field’s scale. The American Society of International Law, the field’s main US learned society, connects students, scholars, and practitioners across members and maintains the standard career guide for entering the specialty.

Who are some well-known International Lawyers ?

Well-known international lawyers include Amal Clooney, Philippe Sands, Rosalyn Higgins, Benjamin Ferencz, Payam Akhavan, and Geoffrey Robertson. Their careers span human rights advocacy, cases before the International Court of Justice, the Nuremberg trials, and the leadership of international tribunals.

Six of the field’s best-known figures are the following:

  1. Amal Clooney: a London-based barrister who has represented clients in international human rights and press-freedom cases before international courts and UN bodies.
  2. Philippe Sands: a professor and barrister who has appeared as counsel in numerous cases before the International Court of Justice and wrote the acclaimed book East West Street on the origins of genocide and crimes against humanity.
  3. Rosalyn Higgins: the first woman elected a judge of the International Court of Justice and later the first woman to serve as its President, from 2006 to 2009.
  4. Benjamin Ferencz: a chief prosecutor at the Nuremberg trials at age 27 who spent the rest of his life, until his death in 2023, campaigning for the International Criminal Court.
  5. Payam Akhavan: a former UN war-crimes prosecutor and professor who has served as counsel in cases before the International Court of Justice.
  6. Geoffrey Robertson: a founder of Doughty Street Chambers in London who served as an appeals judge at the UN Special Court for Sierra Leone.

The list shows the field’s range: courtroom advocates, judges, prosecutors, and scholars all carry the same title. It also shows the long arc; several of these careers span 5 decades, because reputation in international law compounds slowly and lasts.

How can Lexinter help in finding International Lawyer?

Lexinter helps you find an international lawyer through its US attorney directory, which lets you search by practice area, state, and city to locate an international attorney near me with verified profiles. The directory connects individuals and businesses with counsel experienced in cross-border matters at no cost to the searcher.

Start at the Lexinter homepage and search by practice area and location. Directory profiles show each attorney’s practice focus, jurisdiction, and contact details, so you can shortlist counsel whose experience matches your matter, whether it is a cross-border contract, an immigration question, or an international dispute.

Match the lawyer to the matter, not the label. For a foreign acquisition, look for corporate counsel with cross-border deal experience; for a treaty or sanctions question, look for practitioners with government or trade backgrounds; for a family or visa matter that crosses borders, an immigration-focused attorney is the right first call. Our hub on types of lawyers by field maps each specialty so you start the search in the right column.

Attorneys practicing international law can also list their profiles in the directory to reach clients searching for exactly these skills. Either way, the goal is the same: shorten the distance between a cross-border problem and the lawyer trained to solve it.

Sources and notes. The definition and domain of international law follow the United Nations, Uphold International Law (international law defines the legal responsibilities of States in their conduct with each other and their treatment of individuals within State boundaries; more than 560 major multilateral treaties are deposited with the Secretary-General; the International Law Commission has 34 members).
