The Trump administration is seeking to close nearly two dozen U.S. Citizenship and Immigration Services field offices around the world in a move it estimates would save millions per year. But critics argue the closures will further slow refugee processing, family reunification petitions and military citizenship applications.

The USCIS field offices currently assist with refugee applications, family reunification visas and foreign adoptions. They also consider parole requests from people outside the U.S. for urgent humanitarian reasons and process naturalization documents for military members who marry foreign nationals, among other responsibilities.
