How to Apply for USA Citizenship
Dual Citizenship: the status of an individual who is a citizen of two or more nations
The concept of dual citizenship recognizes that a person may have and exercise rights of nationality in two countries and be subject to the responsibilities of both. The mere fact that he/she searched the right of one citizenship does not mean that he/she renounces the other.
Nonetheless, official U.S. policy has been to discourage the incidence of dual nationality. The Government accepts but does not recognize or approve of dual nationality. The Government accepts it: "only as the result of separate conflicting laws of other countries."
The only restrictions on dual nationals who are U.S. citizens are that nonimmigrant visas cannot be issued to U.S. citizens and they must enter the U.S. with a U.S. passport.
The following is a partial list indicating which countries recognize dual citizenship. The list is based primarily on a survey of every country in the world. The question presented was "If a citizen of (the country in question) acquires U.S. citizenship, does he or she retain or lose (the country in question's) citizenship? In the list below, "Retain" means that the individual DOES NOT lose his or her prior citizenship upon naturalizing in the U.S. "Lose" means that the individual DOES lose his or her prior citizenship. Where possible, the list in annotated to provide additional relevant information.
If a country is not listed, it either did not respond to the survey or there was no information otherwise available.
