The U.S. doesn’t recognize “dual” citizenship.
“The U.S. doesn’t recognize ‘dual’ citizenship.”
Not so. If you are born a citizen of the U.S. and one or more other coutries, or if you assume the citizenship of another country without renouncing U.S. citizenship, our government allows you dual citizenship for your entire life.
Even if Obama wasn’t born on U.S. soil (and that’s a big “if”), wasn’t his mother a U.S. citizen? That would also make Barrack a natural-born citizen.
