Yes, a marriage performed in the Bahamas is fully legal and recognized in the United States, provided you follow the high-fidelity legal requirements of the Commonwealth of The Bahamas. To be legally wed, couples must apply for a marriage license at the Registrar General's office in Nassau after being in the country for at least 24 hours. You will need to provide "High-Fidelity" documentation such as valid passports and, if applicable, original divorce decrees or death certificates. Once the ceremony is performed by a licensed marriage officer and the marriage is registered, you receive a Bahamian marriage certificate. Because the Bahamas is a signatory to the Hague Apostille Convention, you may need to obtain an Apostille on your certificate for it to be accepted for certain high-fidelity administrative tasks in the U.S., like changing your name on a Social Security card or passport. As long as the marriage was legal where it was performed, the U.S. government recognizes it as a valid legal union.
