The bill that seeks to prohibit dual citizenship for American citizens directly conflicts with precedents from the United States Supreme Court. The proposal calls for the automatic loss of American citizenship. for those who retain another nationality and do not make a formal choice within one year.
Introduced by Republican Senator Bernie Moreno, the measure establishes that U.S. citizens "must pledge exclusive loyalty to the United States." If an individual does not declare the renunciation of one of their nationalities, they will automatically lose their American citizenship.
