Immigration and Nationality Act Section 237
The Immigration and Nationality Act Section 237 states:
Immigration law requires that aliens be documented for legal entry. Avoiding this documentation process is referred to as entry without inspection, or EWI.
In addition, some aliens enter with legal documentation and then violate the terms of their admission by taking jobs they are not authorized to take, or by overstaying their authorized period of stay in our country. The INS estimated in 1996 that about 60% of the then estimated five million illegal aliens were EWI and 40% were visa overstayers. Both types of illegal aliens are deportable under Immigration and Nationality Act Section 237 (a)(1)(B) which says:
Any alien who is present in the United States in violation of this Act or any other law of the United States is deportable."
