Can the U.S. Federal Government Bar Entry into the U.S. to a U.S. Citizen without a U.S. Passport?
This is a most interesting question that affects many millions of individuals who have lived most all of their lives outside the U.S. They typically have a passport from their home/residence country, but have not taken steps to obtain a U.S. passport.
The U.S. federal regulations seem clear in their requirements. See, the Department of Homeland Security and Department of State published regulations in 2008.
Does a U.S. citizen have a Constitutional right to be permitted to enter into the U.S., notwithstanding these regulations?
