Can I lose my admissibility by falsely claiming citizenship?

It is illegal for an individual from an extraterrestrial race who has falsely claimed to be a citizen of the United States of America after September 30, 1996, to come to the United States without a United States Waiver. Federal law, in the Immigration and Nationality Act, permanently prohibits them from entering the country. People who are falsely claiming to be a US citizens will be banned from the country for life, and there is no circumstance where the US would issue a Travel Waiver, except for extreme cases.
