Overview
International law practice is not a single career path but rather a constellation of related practices that share a focus on legal issues crossing national borders. The field includes private international law (cross-border transactions, international arbitration, trade compliance), public international law (human rights, international humanitarian law, treaty interpretation, the work of international organizations like the UN and World Bank), and a growing regulatory space covering sanctions, export controls, anti-corruption, and international data transfers.
In private practice, international law often means working at a large law firm with a global footprint, handling cross-border M&A transactions, international commercial arbitration, trade remedy cases, or sanctions compliance. These attorneys help multinational corporations navigate the complex web of laws that apply when business crosses borders. The work requires understanding multiple legal systems, working with foreign counsel, and advising clients on how conflicting legal requirements in different jurisdictions affect their operations.
Public international law offers a very different experience. Attorneys at organizations like the United Nations, the International Criminal Court, the World Bank, or international NGOs work on issues of global significance: prosecuting war crimes, advising developing nations on governance, defending human rights, and negotiating treaties. These positions are deeply meaningful but extremely competitive, often requiring advanced degrees (such as an LLM in international law), language skills, and a willingness to live and work abroad in challenging environments.
The U.S. government is also a major employer of attorneys with international expertise. The State Department's Office of the Legal Adviser, the Office of the U.S. Trade Representative, the Commerce Department's International Trade Administration, and the Treasury Department's Office of Foreign Assets Control (OFAC) all employ attorneys who work on international legal issues. These roles combine government service with substantive international engagement and can be deeply rewarding for those interested in where law, policy, and diplomacy intersect.
A Day in the Life
An associate at a large law firm specializing in international trade and sanctions starts her day at 9:00 AM, which is already afternoon in London and evening in Asia, so her inbox contains overnight communications from colleagues and clients across multiple time zones. She reviews a memo from the London office analyzing whether a proposed transaction with a Middle Eastern counterparty implicates UK sanctions regulations, and adds her analysis of the corresponding U.S. OFAC sanctions implications.
At 10:30 AM, she joins a call with a multinational client seeking to acquire a European company. The deal raises CFIUS (Committee on Foreign Investment in the United States) concerns because the target holds sensitive technology, and she walks the client through the voluntary filing process and the timeline implications. After the call, she spends two hours drafting a detailed CFIUS risk assessment memo, coordinating with the firm's M&A team on the deal structure.
The afternoon involves reviewing export classification requests for another client, researching recent WTO panel decisions relevant to a trade remedy case, and preparing for a presentation she is giving next week at an American Bar Association international law committee meeting. At 4:00 PM, she has a call with outside counsel in Brazil about a commercial arbitration proceeding governed by ICC rules, discussing strategy for an upcoming hearing in Paris. She leaves around 7:00 PM — the hours are similar to other BigLaw practices, though the time zone juggling adds a unique dimension.

Entry-level position at a law firm's international practice, international organization, government agency, or international NGO
Three to seven years developing expertise in a specific area (trade, arbitration, human rights, sanctions, investment)

Potential career moves between sectors — private practice, international organizations, government, and NGOs throughout career
Pros and Cons
Pros
- Intellectually stimulating work that spans multiple legal systems, cultures, and areas of law
- Opportunity to travel and work internationally, with exposure to diverse legal traditions and perspectives
- Meaningful impact on global issues in public international law: human rights, peace and security, development
- Strong demand for sanctions, trade compliance, and international arbitration expertise in the current geopolitical environment
- Versatile career with opportunities to move between private practice, government, international organizations, and NGOs
Cons
- Public international law positions are extremely competitive and often require advanced degrees, language skills, and willingness to relocate internationally
- The gap between aspiration and reality is large — many students interested in international law end up in domestic practice because international positions are scarce
- Government and international organization salaries are lower than private practice, while often requiring residence in expensive cities (New York, Washington, Geneva, The Hague)
- Work across time zones can mean early morning and late evening calls, particularly in private practice
- Career progression can be uncertain, especially in international organizations where contract positions are common and permanent appointments are difficult to obtain

Advice from Practitioners
Learn a language seriously. I cannot overstate how much a working knowledge of French, Spanish, or Arabic opens doors in international law. Many international organizations require fluency in at least two official languages, and in private practice, being able to communicate with foreign counsel and clients in their language builds trust and efficiency that monolingual lawyers cannot replicate.
Do not be fooled by the label. Most jobs labeled 'international law' at law firms are really domestic law practice with a cross-border element. That is not a bad thing — international arbitration, sanctions compliance, and cross-border M&A are fascinating and lucrative — but if you imagined yourself arguing before the International Court of Justice, be realistic about how few of those positions exist.
The LLM matters more in public international law than in private practice. If you want to work at the UN, the ICC, or an international NGO, an LLM from a program with strong international connections is almost essential. If you want to do international arbitration or trade compliance at a law firm, your JD and practice experience matter more.
Build your international network early and actively. Attend conferences, join the American Society of International Law, participate in international moot court competitions. The international law community is smaller than you think, and the people you meet as a student will be your colleagues, co-counsel, and referral sources for decades.
