If you marry a U.S, citizen, you wonât be eligible for U.S. citizenship right away. But you may become eligible for a U.S. green card, which can lead to U.S. citizenship. However, there are certain requirements that must be met before you can apply for a green card and ultimately for U.S. citizenship after marriage to a U.S. citizen.
Sorry, but the previous answer is wrong. A US citizen, by birth or by naturalization, remains a US citizen until he or she purposely renounces citizenship before a US consul, or commits one of very few other possible actions WITH THE INTENT of relinquishing US citizenship. The US has no laws against dual citizenship. Spain, on the other hand, does not permit dual citizenship except with the following countries: Bolivia, Chile, Ecuador, Costa Rica, Guatemala, Nicaragua, Paraguay, Peru, the Dominican Republic, Argentina, and Honduras.
