What is international law, why would you study it, and where is the best place to study, intern or work abroad?

What is International law?

• International law examines the rules, institutions, and legal practices that shape relations between states, international organizations, communities, companies, and individuals across borders.
• The field connects legal reasoning with international politics, diplomacy, economics, human rights, security, environmental protection, and the movement of people and goods.
• Studying the discipline involves interpreting treaties, legal judgments, state practice, and competing claims about authority, responsibility, justice, and cooperation.

What are the main reasons for being active in the field of International law?

• To understand how legal rules are created and applied when an issue involves more than one country or legal system.
• To examine how states balance sovereignty with treaty obligations, human rights standards, economic interests, and shared international responsibilities.
• To explore how disputes can be addressed through negotiation, arbitration, courts, tribunals, and international institutions.
• To observe how legal principles operate differently across political systems, regions, languages, and institutional cultures.
• To develop a grounded perspective on global questions such as armed conflict, migration, trade, climate policy, maritime resources, and digital security.

What skills do you need to participate in International law?

• To analyse: international legal questions often require close comparison of treaties, judgments, state conduct, institutional rules, and conflicting interpretations.
• To form an opinion: legal positions need to be developed from evidence and doctrine while taking competing arguments and uncertainties seriously.
• To communicate: the work commonly involves explaining complex rules clearly in legal writing, policy discussions, negotiations, and cross-cultural settings.
• To have integrity: international legal work may involve politically sensitive disputes, confidential information, vulnerable groups, and decisions with consequences across borders.
• To collaborate: cases and policy questions are often handled by teams of lawyers, diplomats, researchers, public officials, translators, and subject specialists.
• To be aware of your surroundings: legal arguments cannot be separated entirely from institutional practice, local history, political relations, and cultural context.
• To act professionally: careful preparation, procedural discipline, discretion, and respect for different legal traditions are central in international environments.

What motivates people to study or work in International law?

• Be and feel meaningful with a sense of purpose: the field often attracts people interested in the legal foundations of peace, accountability, human dignity, and international cooperation.
• Be and feel involved: international law offers a way to engage closely with public questions that affect institutions, communities, and relations between countries.
• Be and feel connected: the discipline places national legal systems within a wider network of treaties, organizations, courts, professional communities, and shared standards.
• Be and feel helpful: some people are drawn to work that supports dispute resolution, legal protection, institutional development, or access to rights.
• Be and feel experienced: studying or interning abroad can deepen understanding of how legal ideas are interpreted within different political, linguistic, and professional settings.
• Be and feel independent and free: the international perspective can appeal to people who prefer to examine legal questions beyond the assumptions of a single national system.

What are the best countries and locations to study, intern or work in International law abroad?

• Countries closely connected with international courts, diplomacy, and European institutions: The Netherlands, Belgium, and Switzerland.
• Countries with influential legal traditions and substantial international academic networks: United Kingdom: England, Scotland to Wales, France, and Germany.
• Countries relevant to international trade, maritime law, finance, and cross-border commercial practice: Singapore, Hong Kong, and Abu Dhabi, Dubai & United Arab Emirates.
• Countries offering perspectives on regional integration, development, human rights, and public-interest law: South Africa, Kenya, and Ghana.
• Countries where environmental, maritime, Indigenous, and Pacific regional questions provide distinctive legal contexts: New Zealand, Fiji, and Australia.
• Countries with important regional, constitutional, migration, and transitional-justice perspectives: Colombia, Argentina, and Costa Rica.
• Locations where international study can be combined with exposure to major legal, diplomatic, and policy communities: New York, London, and Paris.

Where can you find work experience and vacancies for jobs, internships, and voluntary work in International law abroad?

• Legal organizations and administrative work abroad: possible settings include law firms, legal aid organizations, courts, compliance teams, arbitration practices, and organizations handling cross-border cases.
• Government institutions and working in policy abroad: ministries, diplomatic services, regulatory bodies, and public agencies may work with treaties, international obligations, migration, trade, or security policy.
• Civil society organizations and social work abroad: human rights groups and advocacy organizations may offer experience in monitoring, legal research, reporting, public education, and access to justice.
• Research organizations and scientific work abroad: universities, institutes, and policy centers examine legal developments, state practice, international institutions, and emerging global issues.
• Environmental organizations and sustainability abroad: work may concern climate agreements, biodiversity, natural resources, environmental responsibility, and cooperation between jurisdictions.
• Companies and business services abroad: internationally active organizations deal with contracts, trade rules, sanctions, corporate responsibility, data governance, and regulatory compliance.

What are things to consider when studying or working abroad in International law?

• International law is taught through different legal traditions. A programme may emphasize public international law, European law, trade, human rights, arbitration, security, or another specialist perspective.
• Language matters beyond everyday communication. Legal terminology, source materials, court procedures, and institutional working languages can affect which opportunities are accessible.
• Internships may involve research and administrative support rather than courtroom advocacy. The substance of the work depends on the organization, jurisdiction, and level of study.
• Professional qualification remains largely national. An international law degree or internship does not automatically provide authorization to practise law in another country.
• Some organizations handle conflict, displacement, detention, human rights violations, or politically sensitive information. Ethical preparation and realistic expectations are important.
• Visa conditions, confidentiality rules, security procedures, funding, and recognition of academic credits should be checked before committing to a placement.

Further depth: what is International law as a discipline?

What are the main features of International law?

International law provides a framework for conduct across borders. It governs relations among states while also shaping the work of international organizations, courts, companies, civil society groups, and, in some areas, individuals.

• Sovereign equality: states are formally equal as legal entities, even though their political, economic, and military influence differs considerably.
• Consent and legal obligation: many obligations arise through treaties, but international law also develops through customary practice and generally recognized legal principles.
• Decentralized enforcement: there is no single global authority comparable to a national government. Compliance depends on domestic institutions, diplomacy, reciprocal interests, courts, monitoring bodies, and collective action.
• Multiple legal actors: states remain central, but international organizations, tribunals, companies, armed groups, and individuals may also hold rights, duties, or procedural roles.
• Continuing development: established principles are repeatedly applied to new questions involving climate change, cyber operations, artificial intelligence, global health, migration, and shared natural resources.

What are important sub-areas of International law?

The discipline contains overlapping fields. A single dispute may involve treaty interpretation, jurisdiction, human rights, trade, environmental duties, and the responsibility of states or organizations at the same time.

• Law of treaties: concerns how international agreements are negotiated, concluded, interpreted, amended, applied, and terminated.
• Law of the sea: regulates maritime zones, navigation, fisheries, seabed resources, marine research, and the protection of the ocean environment.
• Law of international organizations: examines the powers, procedures, responsibilities, and legal status of bodies created by states.
• International human rights law: establishes standards for the treatment of individuals and provides mechanisms for monitoring and challenging violations.
• International humanitarian law: limits methods of warfare and protects civilians, wounded combatants, detainees, and others affected by armed conflict.
• Use of force and collective security: addresses when force may lawfully be used and how international institutions respond to threats to peace.
• International trade and investment law: governs cross-border commerce, tariffs, market access, investment protection, and related dispute procedures.
• International environmental law: deals with climate obligations, biodiversity, pollution, transboundary harm, and the management of shared resources.
• International criminal law: concerns individual responsibility for crimes such as genocide, crimes against humanity, and war crimes.

What are key concepts of International law?

• Sovereignty: the authority of a state to govern its territory and conduct its affairs, subject to obligations arising under international law.
• Jurisdiction: the legal power to prescribe rules, decide cases, and enforce laws in relation to persons, territory, conduct, or particular interests.
• State responsibility: the framework used to determine when conduct is attributable to a state, when an international obligation has been breached, and what legal consequences follow.
• State immunity: the principle that foreign states and certain state property are protected from another country's courts, subject to recognized limitations and exceptions.
• Treaties: written international agreements governed by international law that create obligations for the parties that have accepted them.
• Customary international law: rules arising from sufficiently general and consistent state practice followed from a sense of legal obligation.
• Peremptory norms: fundamental rules from which no derogation is permitted, regardless of an individual state's consent.
• International Law Commission: a United Nations body that studies, clarifies, and supports the progressive development and codification of international law.
• International Court of Justice: the principal judicial organ of the United Nations, responsible for deciding disputes submitted by states and giving advisory opinions on legal questions.

Who are influential figures in International law?

• Hugo Grotius: the Dutch jurist is closely associated with the early systematic study of relations between states, the law of war and peace, and freedom of the seas.
• Legal scholars and practitioners: the field has developed through the work of jurists, diplomats, judges, treaty drafters, and advocates from many regions rather than through a single intellectual tradition.
• International institutions: courts, commissions, treaty bodies, and diplomatic conferences have become collective centers of legal development by interpreting rules and recording state practice.

Why is International law important?

• Peaceful relations: it offers procedures and shared standards for negotiation, cooperation, dispute settlement, and responses to threats to international peace.
• Protection of people: human rights, humanitarian, refugee, and criminal law establish protections that extend beyond the internal law of a single state.
• Cross-border cooperation: legal frameworks make coordinated action possible in trade, transport, communications, public health, environmental protection, and the management of shared resources.
• Accountability: international rules provide standards by which state conduct, institutional decisions, and in some cases individual actions can be assessed.
• Predictability: agreed procedures and established principles help governments, organizations, and other actors understand the legal consequences of international conduct.
• Common language: even where parties disagree, international law gives them a vocabulary for presenting claims, challenging conduct, and proposing solutions.

How is International law applied in practice?

• Diplomacy and negotiation: governments rely on legal rules when drafting agreements, presenting claims, managing crises, and resolving disagreements.
• International organizations: institutions use treaties and procedural rules to define their mandates, make decisions, monitor compliance, and coordinate collective action.
• Courts and tribunals: international and regional bodies decide disputes, interpret legal obligations, review alleged violations, and issue judgments or advisory opinions.
• Arbitration and mediation: states, investors, companies, and other parties may use specialized procedures to address cross-border disputes outside ordinary domestic courts.
• Domestic legal systems: national legislatures, courts, and public authorities give practical effect to treaties and other international obligations according to domestic constitutional arrangements.
• Legal and policy advice: lawyers and researchers assess proposed decisions, contracts, sanctions, military operations, regulations, and institutional policies for consistency with international law.
• Monitoring and advocacy: civil society organizations, treaty bodies, commissions, and independent experts document conduct and use international standards to support scrutiny and reform.
