Another term for an illegal alien in the U.S. is an undocumented non-U.S. citizen.

Another term for an illegal alien in the U.S. is an "undocumented non-U.S. citizen". To understand this, let's break down the terms:

1. "Illegal alien" refers to a person who resides in a country without legal authorization or proper documentation.

2. "Undocumented" means the person lacks official paperwork to legally reside in a country.

3. "Non-U.S. citizen" indicates that the individual is not a citizen of the United States.

Therefore, combining these terms, an "undocumented non-U.S. citizen" serves as an alternative way to refer to an illegal alien in the U.S.
