St Christopher (St. Kitts) and Nevis recognises both citizenship by birth and citizenship by descent. Individuals born in St. Kitts and Nevis are automatically entitled to citizenship, as are any children of a St. Kitts and Nevis citizen.
Individuals who marry a citizen of St. Kitts and Nevis are also eligible to become citizens, generally following a three-year period of marriage.
St Kitts and Nevis also has in place a Citizenship by Investment Programme whereby individuals from any country, with the exception of Iran and Afghanistan, may invest and obtain citizenship. By virtue of investing in an Approved Real Estate Development in St. Kitts and Nevis or the Sustainable Growth Fund, such individuals would become citizens of St. Kitts and Nevis, as would any dependents included in the application.
The minimum possible real estate investment for the main applicant through the programme is USD 400,000, or no less than USD 200,000 as part of a joint real estate investment accumulating to a minimum of USD 400,000. Otherwise, an applicant can make a minimum donation of USD 150,000 to the Sustainable Growth Fund which supports school construction, education initiatives, mitigating the effects of climate change, small and medium-sized business enterprises, and manufacturing, among many other initiatives.
St. Kitts and Nevis allows dual citizenship with no repercussions. The only restriction related to dual citizenship is that individuals who wish to become Members of Parliament cannot be elected or appointed as members if they are by virtue of their own act, under any acknowledgement of allegiance, obedience or adherence to a foreign power or state.
