From Green Card to Citizenship: Are You Ready to Apply? | Tingen Law

When you can apply

• The five-year rule. Most green card holders can apply after five years as a permanent resident.
• The three-year rule. If you've been married to and living with the same U.S. citizen for the last three years, and they've been a citizen that whole time, you can apply after three.
• The 90-day head start. You can file up to 90 days before you reach either mark. Use the "Resident Since" date on your card to count.

The path

1. You check your dates and your travel, so there are no surprises.
2. You file Form N-400, online or on paper.
3. USCIS takes your fingerprints and photo.
4. You go to an interview, where you take the English and civics tests.
5. You take the Oath of Allegiance at a ceremony and become a U.S. citizen.

Long trips are the number one surprise. Two rules apply, and they're different:

• Physical presence: you need to have been inside the U.S. for at least half the time, which is 30 months out of five years.
• Continuous residence: a single trip of more than six months raises a question, and a trip of a year or more usually restarts your clock.

Here's how that plays out. Maria got her green card on March 15, 2022, so she can file from December 15, 2026. In 2024 she spent seven months in Honduras caring for her mother. That trip doesn't disqualify her automatically. She'll need to show she kept her home, job and life here. You also need to have lived in your state for three months before you file.

The test and interview. The officer checks that you can read, write and speak basic English, and asks civics questions about U.S. history and government. USCIS publishes the full list of questions, so you can study exactly what's asked. If English is the hard part, you may qualify for an exemption. Here's who does.

Key facts

• Form: N-400, Application for Naturalization
• Government fee: $710 online or $760 on paper. A reduced fee or fee waiver may be available depending on household income.

What complicates it

1. Long trips outside the U.S. Trips of six months or more need a closer look before you file. Am I eligible to apply for citizenship?
2. An old arrest, ticket or charge. USCIS asks about every one, even if it was dismissed. Some don't matter and some do. Applying with a record or limited English.
3. Taxes, child support or Selective Service. Unfiled taxes, unpaid child support or a missed Selective Service registration can come up at the interview. Most can be fixed before you file.
