Can you keep your Saint Kitts and Nevis citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Citizens of Saint Kitts and Nevis keep their original citizenship when they become U.S. citizens, because dual nationality is permitted.
What the law says
- Dual nationality has been permitted in Saint Kitts and Nevis from independence.
- Nationals may voluntarily renounce their affiliation only if they are legal adults and able to acquire other nationality, avoiding statelessness.
- Renunciation may be refused if the country is at war with the proposed new nationality's source or if it would threaten the nation.
- Denaturalisation can occur for fraud, treason, disloyalty or service to a foreign government, certain criminal offences, loss of nationality in another Commonwealth country, or failure to meet nationality-by-investment requirements.
“Dual nationality has been permitted in Saint Kitts and Nevis from independence.”
What about the U.S. side?
The United States allows dual citizenship. At the oath ceremony you promise to renounce allegiance to other countries, but U.S. law does not make you formally give up your other passport. The question is only whether Saint Kitts and Nevis lets you keep yours.
