Exclusion (Immigration) Law and Legal Definition

Exclusion is the official term for denying an alien entry into the United States. The denial of entry to the alien can be either through an expedited removal procedure or through removal proceedings in the presence of an immigration judge. There can be several grounds for exclusion procedure. The Immigration and Nationality Act (INA) spells out a strict set of admissions criteria and Exclusion rules for all foreign nationals who come permanently to the United States as immigrants (i.e., legal permanent residents) or temporarily as nonimmigrants.
