Seems US is quickly transforming into a country of indentured servants... far from the home of the brave and land of the free. Exactly how is this going to stop those with dual citizenship? They will bypass this bs and travel on their home country passport.
I believe, technically, the U.S. oath of naturalization precludes maintaining dual citizenship. Therefor, they will arrest Americans attempting to leave the country under a foreign courntry's documents.
