Consular Affairs (CA) is the public face of the Department of State for millions of people around the world. CA is responsible for the welfare and protection of U.S. citizens abroad, for the issuance of passports and other documentation to citizens and nationals, and for the protection of U.S. border security and the facilitation of legitimate travel to the United States. CA also has a significant domestic presence, most notably the 29 U.S. Passport agencies and centers, 26 of which deal directly with the U.S. public. These far-reaching consular activities have broad foreign policy and domestic political implications and involve serious legal, humanitarian, and management concerns. Responsibility for these functions is vested within the Department of State in the Assistant Secretary for Consular Affairs and for their implementation abroad in consular officers assigned to embassies and consulates abroad. CA is also the Department’s largest Bureau in terms of domestic personnel and is almost entirely funded through revenue generated by consular fees. This revenue totaled $4.16 billion in 2015, making CA the equivalent of a Fortune 600 company.
