Yes, if a person who is not a citizen of the United States is convicted of a crime, he or she can be deported. This includes lawful permanent residents who are lawfully living and working in the United States. Under the Immigration and Nationality Act, if a non-citizen is convicted of an aggravated felony, a crime of moral turpitude or any one of a number of listed crimes in a third category (such as violations of laws relating to domestic violence, controlled substances and possessing a firearm), he or she is at risk of deportation. In addition to deportation, a conviction may adversely affect a lawful permanent resident’s ability to become a United States citizen.
