Department of State

The U.S. Department of State is America’s lead foreign affairs agency, responsible for conducting U.S. foreign policy and diplomatic relations with countries around the world. Established in 1789 as the first administrative arm of the federal government, the State Department handles everything from negotiating international treaties and representing the U.S. at the United Nations to protecting American citizens abroad and issuing travel documents. With 271 diplomatic posts worldwide and thousands of dedicated professionals, the department plays a critical role in advancing American security, prosperity, and democratic values globally.

Travel Documents and Visas

One of the State Department’s most visible services is issuing passports and visas to Americans and foreigners alike. Whether you need to apply for a passport for the first time or renew an existing one, the State Department guides Americans through the process. You can apply for both a passport book and card, and if you need your document quickly, expedited services are available. For families, the Family Passport Guide provides step-by-step help for getting children their travel documents. The department also handles special situations, such as passport name changes and replacing damaged passports. For those traveling internationally, understanding the difference between passports and visas is essential, and foreigners seeking entry need to meet visa requirements, which they can track once submitted.

International Travel and Safety

The State Department helps Americans travel safely and responsibly worldwide. Before you go, check U.S. travel advisories to understand travel risk levels by country. Consider enrolling in the Smart Traveler Enrollment Program (STEP) to receive important updates about conditions in your destination. Once abroad, the State Department is ready to assist—whether you need help handling emergencies, are dealing with a lost passport overseas, or have other urgent needs while traveling.

Diplomacy and Foreign Policy

Beyond individual services, the State Department is central to how America shapes its role in the world. The Secretary of State serves as the President’s principal foreign policy advisor and implements diplomatic strategy globally.
