Can you keep your Saint Lucia citizenship when you become a U.S. citizen?
Allowed with conditions
Only in some cases
Most Saint Lucian citizens keep their citizenship when they become U.S. citizens, but citizens by ordinary naturalisation generally lose it unless they were Irish citizens at naturalisation.
What the law says
- Since independence, Saint Lucia has allowed dual nationality for all citizens other than by ordinary naturalisation.
- Citizens by ordinary naturalisation may have multiple citizenship only if they were a citizen of the Republic of Ireland at the time of their naturalisation.
- Applicants for ordinary naturalisation must, unless they are citizens of the Republic of Ireland, renounce their citizenship of origin.
- Nationals may voluntarily renounce their Saint Lucian affiliation if they are legal adults of full capacity.
- Renunciation may not be accepted if Saint Lucia is at war with the proposed new source of nationality.
“Saint Lucia has allowed dual nationality for all citizens other than by ordinary naturalisation.”
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 Lucia lets you keep yours.
