U.S. Citizenship & Naturalization FAQs

How long does the naturalization process take?
Processing times vary, but it typically takes between 8 to 14 months from the time you file to your oath ceremony.

What happens if I fail the English or civics test?
You’ll be given a second opportunity within 60 to 90 days to retake the portion of the test you did not pass.

Can I travel abroad while my application is pending?
Yes, but extended trips may affect your continuous residence requirement. Always consult an attorney before long travel during the process.

Do I need to bring original documents to my interview?
Yes. USCIS requires original documents such as your green card, passport, and other records.

What is considered “good moral character”?
USCIS reviews your criminal, financial, and personal history. Issues like unpaid taxes or certain convictions can affect your eligibility.

Is dual citizenship allowed?
The U.S. does not require you to give up citizenship in your home country, but whether you can keep it depends on the laws of your original country.

Can I apply for citizenship if I’m married to a U.S. citizen?
Yes. You may apply after 3 years of permanent residency, as long as you’ve been living with your spouse during that time.
