Frequently Asked Questions (FAQs)

How much is the fee for filing Form N-400?

The total cost of the application is roughly $725.

Do I need a lawyer to apply for US Citizenship?

No, you do not need a lawyer to use Form N-400 to apply for naturalization. You may file USCIS forms on your own, though having a lawyer or other legal professional to consult may prove beneficial.

Does USCIS publish the naturalization test questions?

Yes, USCIS does publish a complete list of the civics tests from 2008 and 2020. Copies of these tests can be found on their site.

Does the USCIS provide study materials for the naturalization test?
Yes. These materials are available for free on their site, with separate sets of study materials for the 2008 and 2020 tests.

Does the USCIS change the questions on the test frequently?

No. However, some answers may change based on recent elections or political appointments, so it is best to keep track of the current information whenever possible.

Will all of the questions in the civics tests be asked during the interview?

No, but it is important to review them all regardless in order to ensure that you are fully prepared regardless of what questions the interviewer chooses to ask.

Can I live in both my home country and the US at the same time before submitting Form N-400?

Not entirely. Submitting Form N-400 requires that you have lived in the US for at least 5 years before submitting Form N-400. You may still travel to another country as long as you are not legally disallowed from doing so, but if the trip lasts 180 days or longer, the USCIS may determine that you no longer meet the requirements to be eligible for naturalization.

Will the USCIS approve my Form N-400 when I pass the reading, writing, and civics parts of the test?

No. There remains the speaking portion of the test, as well as all other requirements for the naturalization process.

Can I legally change my name while my naturalization application is pending?

Yes. However, you must immediately provide USCIS with the documents that legally changed your name, such as a marriage certificate, divorce decree, court order, or other official legal record. Make sure to mention your name change and bring the related documents when you come in for your interview.

Do I need to bring original documents to the naturalization interview?

Yes. Consult the USCIS site on what documents you need to bring original copies of. This is done in order to prevent fraud.

What do I do if I have already applied for naturalization, but my Green Card is expiring?

Any naturalization applicant who properly submits Form N-400 after Dec 12, 2022 will receive a Form N-400 receipt notice that automatically extends the validity of a person’s Green Card for 24 months from the card expiry date. This receipt notice must be presented to show that your Green Card has been extended. Otherwise, you must file Form I-90 in order to renew your Green Card.

Will I be allowed to retake the test if I fail portions of it?

You will be given two opportunities to meet the English and Civics requirements. Failure to pass any portion of these assignments will require that you be retested on that portion or portions during a new interview between 60 to 90 days from the date of your initial interview.

How many times can I apply for naturalization?

There is no limit to the number of times you can file for naturalization, but there is a fee that must be paid per Form N-400 that you submit to the USCIS.

Can I file for naturalization before I have lived in the US for 5 years?

Yes, but only if you have lived in the US for at least 3 years and are married to a US citizen.

Am I ineligible for naturalization if I receive public assistance?

No. As long as these benefits were received lawfully, they will not have any bearing on your eligibility for naturalization.
