Deferred Inspection

See "Parolee"

Deportable Alien

An alien in and admitted to the United States subject to any grounds of removal specified in the Immigration and Nationality Act. This includes any alien illegally in the United States, regardless of whether the alien entered the country by fraud or misrepresentation or entered legally but subsequently violated the terms of his or her nonimmigrant classification or status.


The formal removal of an alien from the United States when the alien has been found removable for violating the immigration laws. Deportation is ordered by an immigration judge without any punishment being imposed or contemplated. Prior to April 1997 deportation and exclusion were separate removal procedures. The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 consolidated these procedures. After April 1, 1997, aliens in and admitted to the United States may be subject to removal based on deportability. Now called Removal, this function is managed by U.S. Immigration and Customs Enforcement.

Derivative Citizenship

Citizenship conveyed to children through the naturalization of parents or, under certain circumstances, to foreign-born children adopted by U.S. citizen parents, provided certain conditions are met.

Each District Office, headed by a District Director, has a specified service area that may include part of a state, an entire state, or many states. District Offices are where most USCIS field staff are located. District Offices are responsible for providing certain immigration services and benefits to people resident in their service area, and for enforcing immigration laws in that jurisdiction. Certain applications are filed directly with District Offices, many kinds of interviews are conducted at these Offices, and USCIS staff is available to answer questions, provide forms, etc.
