The time it takes to be naturalized varies by location. USCIS is continuing to
modernize and improve the naturalization process and would like to decrease the time it takes to an average of 6 months after the Form N-400 is filed
If you are not a U.S. citizen by birth or did not acquire/derive U.S. citizenship automatically after birth, you may still be eligible to become a citizen through the Naturalization process. Eligible persons use the “Application for Naturalization” (Form N-400) to apply for naturalization.
Your time as a Permanent Resident begins on the date you were granted permanent Resident status. This date is on your Permanent Resident Card (formerly known as an Alien Registration Card or “Green Card”).
The letter sent to you with details about your interview appointment will also provide you information on how to change the date. But you should know that changing the date can delay your application process by months.
You may check the status of your naturalization application by visiting www.uscis.gov or by calling Customer Service at 1-800-375-5283 (TTY: 1-800-767-1833).
