Adds immigration penalties tied to trespassing on U.S. military, naval, or Coast Guard property. A noncitizen who is convicted of, or who admits committing acts that meet the elements of, the federal offense in 18 U.S.C. 1382 becomes inadmissible to the United States. A noncitizen convicted of that offense also becomes deportable.

“Inadmissible” means visas can be refused and entry denied; “deportable” means a person already in the U.S. can be removed. The bill does not change the criminal penalties for trespass itself; it only adds immigration consequences and places these rules in the Immigration and Nationality Act.
