In McAllen, U.S. Citizenship and Immigration Services assisted an investigation that resulted in the denaturalization of Carlos Noe Gallegos, a Mexican national and convicted child sex offender who fraudulently obtained U.S. citizenship by concealing prior criminal conduct during his 2010 naturalization process. The U.S. District Court for the Southern District of Texas determined that Gallegos’s undisclosed sexual assault of a child rendered him ineligible for citizenship and ruled that it had been illegally obtained. The case was handled by the Department of Justice Office of Immigration Litigation with support from the U.S. Attorney’s Office for the Southern District of Texas, and was investigated by ICE Homeland Security Investigations with assistance from USCIS.
