- Moving a language exam
- Moving a test of governmental, historic, and cultural knowledge
- Keeping a legitimate visa or residency license (usually a permanent resident document) during the time of application
- Having on a clean record that is criminal
- Using an oath of citizenship (showing dedication to your used country)
- Renouncing previous citizenship(s), unless your used nation acknowledges double citizenship for naturalized citizenship
Numerous nations, including most developed nations, recognize double citizenship (also called double nationality) for naturalized residents. You don’t necessarily have to renounce your American citizenship, as is generally the case when you obtain citizenship in a country that doesn’t recognize dual citizenship if you obtain citizenship in one of these countries. Notable nations which do not recognize citizenship that is dual naturalized residents consist of Germany, Austria, holland, Japan, Norway, and Singapore.
As being a citizen that is dual of U.S. and a different country, you can easily carry passports from both nations, enjoying all of the rights and privileges afforded to single-nationality residents. Needless to say, you’ll want to comply with each country’s regulations and responsibilities, including (in a few situations) compulsory armed forces conscription or service that is public.
