All non-U.S. Citizens who are living in the U.S. could be subject to deportation if they violate the terms of their stay or commit certain crimes. Even individuals who have been legal permanent residents for many years can still be placed into deportation proceedings if they violate the terms of their stay. On the other hand, U.S. Citizens cannot be placed in deportation nor can they be denied entry into the United States..

.

Therefore, it is advisable that persons eligible to apply for citizenship do so as soon as they are can.
