Under U.S. immigration law, a country such as El Salvador can accept someone deported from the U.S. who isn’t a citizen of that country if the person’s homeland refuses to accept them, says Theresa Cardinal Brown, a former homeland security official under the administrations of Presidents George W. Bush and Barack Obama.

El Salvador has offered to take in people deported from the U.S. for entering the country illegally as well as the country’s violent criminals — even if they’re American citizens

Secretary of State Marco Rubio said he is reviewing an offer from the president of El Salvador to deport not just undocumented immigrants but also American prisoners to a mega-prison in the South American country.
