This is general information, not legal advice. This page is about green card holders applying for citizenship. If you have DACA, see What counts as continuous residence for DACA? instead.

What is continuous residence?

To become a citizen, you usually must have lived in the U.S. as a green card holder for 5 years, or 3 years if you are married to and living with a U.S. citizen. "Continuous residence" means you did not break that time with a long stay abroad.

It is separate from physical presence. You also need to have been physically in the U.S. for at least half of that time: 30 months out of 5 years. And you must have lived for 3 months in the state or USCIS district where you apply.

Do short trips count against me?

Not on their own. If no single trip lasted more than 6 months, USCIS does not presume a break. But be careful: many trips just under 6 months each can still add up to a break, and they eat into your physical presence days.

You can file Form N-400 up to 90 days before you reach your 5 or 3 years, as long as you meet the other rules (USCIS N-400 page).

What if I was gone 6 months to a year?

USCIS presumes the trip broke your continuous residence. You can push back with proof that your life stayed here. USCIS names examples like these:

  • You did not quit your U.S. job, and you did not take a job abroad.
  • Your close family stayed in the U.S.
  • You kept your home here, or kept full access to it.

Gather papers that show this: pay stubs or a letter from your employer, your lease or mortgage, and proof that your family lived here. One warning: claiming to be a "nonresident" on your taxes can raise questions about whether you gave up your green card.

What if I was gone a year or more?

A trip of one year or more breaks continuous residence automatically. For the usual 5 year path, you must wait at least 4 years and 1 day after you come back before you apply. For the 3 year path (married to a citizen), it is 2 years and 1 day. Even then, you may need to show you did not break residence.

A year away can also put your green card at risk. A green card works for coming back only after a trip of less than one year. A reentry permit, filed on Form I-131 while you are still in the U.S., can help protect your status on a long trip. It lasts up to 2 years. It helps show you did not give up your green card. It is not the same as Form N-470, the form that can preserve residence for citizenship for some jobs abroad (see below). USCIS explains the options on its International Travel as a Permanent Resident page. The federal fee rule lists the reentry permit fee at $630 (8 CFR 106.2(a)(7)). Check the USCIS fee schedule the day you file.

Can I keep my residence while I work abroad?

Sometimes. Form N-470 can preserve continuous residence for green card holders doing certain kinds of work abroad. It has strict rules and timing. Talk to a lawyer before you take the job.

What should I do before my next trip?

  1. Count your days. Keep a simple list of every departure and return.
  2. Keep your ties here. Keep your job, home, bank account and tax filings as a U.S. resident.
  3. Plan around 6 months. Stay under 6 months per trip when you can.
  4. Going a year or more? Ask about a reentry permit, and file it before you leave.
  5. Have a criminal case? Do not travel until a lawyer says it is safe. See Green card holders: should I travel abroad with pending charges?

What does this look like with real dates?

A made up example, not a real case. Rosa got her green card on May 1, 2022. She plans to apply on the 5 year path.

  • In 2023 she spent 8 months in Guatemala caring for her mother. That trip is over 6 months, so USCIS presumes a break.
  • She kept her job in San Mateo on approved leave, her husband and kids stayed in their apartment, and she filed taxes as a U.S. resident. She saves her leave letter, her lease and her tax returns. These are the kinds of proof USCIS names to rebut the presumption.
  • Her total time abroad in the last 5 years is about 9 months, so she still has more than 30 months inside the U.S.
  • Her 5 years are up on May 1, 2027. She can file up to 90 days before that, so from January 31, 2027.
  • She brings her travel list and her proof of ties to a free clinic before she files.

If Rosa's 2023 trip had lasted 13 months, the break would be automatic. She would have to wait at least 4 years and 1 day after her return before filing.

What does it cost to apply for citizenship?

The Form N-400 fee is $760 on paper or $710 online. A $380 reduced fee is available, on paper, if your household income is at or below 400% of the federal poverty guidelines. A fee waiver is also still available for some people (USCIS fee schedule, checked October 21, 2026). A rule proposed in June 2026 would raise these fees and end the waiver and reduced fee, but it is not final. See How much citizenship costs and how to get a fee waiver or reduced fee
