International law is broad in its conception and can be broken down into private and public sectors. In the private sector, specialists in international law may work in finance and trade divisions of multinational corporations. Familiarity with business essentials, as well as corporate law or intellectual property law would be helpful in this field. In the public international law, practitioners would work on cases that involve dealings between sovereign nations. Familiarity with comparative law or public international law would be most helpful for effective practice in this field. Both private and public international law are interdisciplinary in nature and would involve an understanding of the differences between common law and civil law systems across borders.
