Frequently asked questions

U.S. citizenship questions people ask us most

No. Citizenships.id is an information resource focused specifically on the path to U.S. citizenship. We are not a law firm, we do not practice law, and using this site does not create an attorney-client relationship. We help you understand your general options and, if you choose, connect with a member of our staff or a licensed attorney.

Generally 5 years of continuous permanent residence, or 3 years if you're married to and living with a U.S. citizen — assuming you also meet the physical presence and good moral character requirements. Military service can change this timeline in some cases.

Generally, a USCIS officer reviews your N-400 application with you, asks questions about your background, and administers the English and civics test in the same appointment. Reviewing your own file beforehand for consistency generally helps.

Generally yes — U.S. law does not require you to give up another citizenship to naturalize. However, some other countries have their own rules about dual citizenship, so it's worth checking your home country's position too.

It depends on the child's age, immigration status, and where they're living at the time — some children acquire citizenship automatically under current rules, while others may need a separate application. This is a fact-specific area worth confirming directly.

Generally, if you don't pass a portion of the test at your first interview, USCIS gives you another opportunity to be retested on that portion within a set window, rather than starting the whole application over.

The information on this site, the tools, and the AI assistant are free to use. A consultation with a member of our staff is also typically free and without obligation.
