Naturalized citizens who have committed a crime after obtaining such status are generally not subject to deportation. However, it is possible that a naturalized citizen could lose citizenship status for a variety of reasons. In the event that people have made material misrepresentations during the naturalization application application, the government could move for denaturalization and eventual deportation.
In the past, those who were found to be affiliated with the Nazis during World War II have had their citizenship revoked. Citizenship can also be revoked from individuals who have affiliated with a communist or terrorist regime within five years of becoming a citizen. Furthermore, anyone who is dishonorably discharged from the military may be deported if the discharge happens within five years of the start of their military service. If such an event occurs, an individual may be deported back to his or her former home country.
As long as naturalized citizens have been honest about their pasts, it is difficult for them to lose their rights as an American. It is in most cases unlikely that they would be deported for committing a crime after becoming a citizen regardless of whether the crime was a felony or a misdemeanor.
Those who are going through deportation proceedings for whatever reason may wish to talk to an immigration attorney as soon as possible. An attorney may be able to review the case and then determine how it would impact the person's immigration status. Anyone who is not a naturalized citizen may be subject to deportation after committing a crime regardless of its severity. However, legal counsel may be able to show that the incident was an isolated one and that steps have been taken to prevent it from happening in the future.
