Physically removed Americans from the United States

A number of Americans have been placed in immigration detention centers to be deported but were later released.[15][16] Up to one percent of all those detained in immigration detention centers are nationals of the United States according to research by Jacqueline Stevens, a professor of political science at Northwestern University.[21]

The following is an incomplete list of Americans who have actually experienced deportation from the United States:

Pedro Guzman, born in the State of California, was forcefully removed to Mexico in 2007 but returned several months later by crossing the Mexico–United States border. He was finally compensated in 2010 by receiving $350,000 from the government.[22] Mark Daniel Lyttle, born in the State of North Carolina, was forcefully removed to Mexico but later returned to the United States from Guatemala and filed a damages lawsuit in federal court,[13] which he ultimately won.[2] Andres Robles Gonzalez derived U.S. citizenship through his U.S. citizen father before being forcefully removed to Mexico. He was returned to the United States and filed a damages lawsuit in federal court, which he ultimately won.[3][23] Roberto Dominquez was born in Lawrence, Massachusetts. He was deported to the Dominican Republic. The government is unconvinced in this case as it claims that there are two people by the same name, both born during the same month and year. According to the government, both children were born to parents with the same addresses, and that one child was born in Santo Domingo, the capital of the Dominican Republic.[24] Esteban Tiznado-Reyna was born in Mexico to a father who had an Arizona birth certificate, which was found unreliable in an immigration court.[25] Tiznado was found not guilty of illegal reentry into the United States in 2008, but ICE still deported him despite the verdict. Documents were uncovered that the USCIS withheld in the 1980s, showing his proof of citizenship.[24]
