Quick question.
British Permanent Resident - can I apply for US citizenship and keep my British citizenship and have dual citizenship to both countries?
This is not a problem, UK citizenship is not abandoned when applying for and becoming a US citizenship. US and UK recognize dual citizenship.
Dual Citizenship and the Loss of Citizenship
Many countries permit or even encourage the acquisition of another country's citizenship, while others allow dual (or multiple) citizenship only if the other citizenship is not acquired voluntarily. Still other countries do not permit dual citizenship and have provisions in their laws concerning the loss of citizenship when another nationality is acquired. In the United States, dual citizenship is not explicitly prohibited; the United States has no laws or policies addressing this issue. (Dual citizenship is discussed in more detail in Section VI.)
U.S. Policy
The current citizenship and immigration laws of the United States do not specifically address dual nationality. According to the State Department, “the U.S. Government recognizes that dual nationality exists but does not encourage it as a matter of policy because of the problems it may cause.ť The State Department notes that problems may arise from
- claims of other countries on dual national U.S. citizens that may conflict with U.S. law;
- conflicts that arise from a dual national's allegiance to both the United States and the foreign country;
- dual nationals are required to obey the laws of both countries, which may be in conflict; and
- each country having the right to enforce its laws, particularly when the dual national is in that country.
Further, U.S. Government efforts to assist its dual citizens abroad may be limited. In particular, the country where a dual national is located generally has a stronger claim to that person's allegiance.
International Comparisons
In contrast to the U.S. law, Canadian law specifically addresses dual citizenship. Amendments to Canada's citizenship law, effective February 15, 1977, permit Canadian citizens to retain their Canadian citizenship if they acquire a foreign nationality. Several other countries also generally permit dual citizenship, including Australia, France, Mexico, Spain, Switzerland, and the United Kingdom.
