What is Form N-400?

Form N-400, “Application for Naturalization”, is the application that green card holders use to apply for U.S. citizenship after meeting some requirements that will be mentioned below.

If your biological or legal adoptive father or mother was naturalized before you reached your 18th birthday or is already a U.S. citizen by birth, you may already be a U.S. citizen.

You can file Form N-400

If you’re at least 18 years old or older at the time, are a lawful permanent resident (“green card”), demonstrate continuous permanent residence in the United States for at least 5 years, prove that you have been physically present in the United States for at least 30 months, and show that you have lived for at least 3 months in the state where you are applying.

You may file form N-400 online if:

  • You have a green card.
  • You demonstrate continuous permanent residence in the U.S. for at least 5 years.
  • You demonstrate that you have been physically present in the U.S. for 30 months.
  • You demonstrate that you have lived at least 3 months in the state where you’re applying.

You may NOT file form N-400 online, only by mail if:

  • You’re applying based on your military service
  • You’re applying from outside the U.S.
  • You’re applying for a reduced fee or a fee waiver.

We are designed to be intuitive and simplify complex and confusing immigration processes.

To better illustrate you we’ve come up with some brief examples:

Carlos is a lawful permanent resident in the United States and his brother José is interested in migrating to the U.S. Can José file form I-130 for his brother José?
  • Carlos would not be able to file petition form I-130 because only U.S. Citizens can file for siblings.
Maria is a U.S. Citizen and her mother Karen lives in Mexico. Can Karen qualify for relative status?
  • Yes, Maria can file form I-130 for her mother Karen as well as for her father, siblings, and children.
Alex is a U.S. Citizen and he married a foreign national (Melissa). Is it possible for Melissa to apply for a green card?
  • Yes, Alex can be Melissa’s petitioner and you also can be your spouse’s petitioner (as long as you’re a U.S. Citizen).

Documents you need to show you are a Citizen or Lawful Permanent Resident:

U.S. Citizen

  • A copy of your birth certificate, issued by a civil registrar or other civil authority showing that you were born in the United States.
  • A copy of your naturalization certificate or certificate of citizenship issued by USCIS
  • A copy of Form FS-240, Consular Report of Birth Abroad (CRBA), issued by a U.S. Embassy or U.S. Consulate.
  • A copy of your unexpired U.S. passport.
  • An original statement from a U.S. consular officer verifying that you are a U.S. citizen with a valid passport.

Lawful Permanent Resident

  • A copy of the front and back of your Permanent Resident Card (Form I-551).​
  • If you have not yet received your card, submit copies of your passport biographic page and the page showing admission as a lawful permanent resident.​
  • Or other evidence of permanent resident status issued by USCIS or the former INS.​

You may NOT file Form N-400 in the following scenarios:

1
You are not a lawful permanent resident, hence you do not have a Green Card.
2
You cannot demonstrate continuous permanent residence in the United States for at least 5 years (it could be less if you're married to a U.S. Citizen).
3
You cannot show that you have been physically present in the United States for 30 months (it could be less if you're married to a U.S. Citizen)
4
You have not turned 18 years of age yet.
5
If you do not show that you have lived for at least 3 months in the state where you are applying.
6
If you acquired citizenship through at least one U.S. citizen parent.
