Understand the 5-year Green Card rule for U.S. citizenship, including continuous residence, physical presence, travel risks, early filing, the 3-year marriage rule, current fees, and key Form N-400 steps in 2026.
How the 5-year Green Card rule works
Most applicants must have been a lawful permanent resident for at least five years before naturalization. The qualifying period generally begins on the resident since date printed on the Green Card, not when an immigrant petition was filed or a priority date became current.
Applicants who obtained permanent residence through adjustment of status generally become residents on the approval date. Different dating rules may apply to refugees, asylees and certain other categories, so the date on the card and the official immigration record should be checked.
Eligibility involves more than completing five calendar years. The applicant must also satisfy requirements involving continuous residence, physical presence, residence within the relevant state or USCIS district and good moral character.
Continuous residence and physical presence
Under the general five-year rule, applicants must maintain continuous residence in the United States throughout the required period and normally until naturalization. They must also have been physically present in the country for at least 30 months during the five years before filing.
Continuous residence concerns whether the United States remained the applicant’s principal home. Physical presence is a mathematical count of the days actually spent inside the country.
An absence of more than six months but less than one year creates a rebuttable presumption that continuous residence was interrupted. Evidence of continued U.S. employment, a home, immediate family ties and other connections may help rebut that presumption.
An absence of one year or longer generally breaks continuous residence unless the applicant qualifies for an approved Form N-470 exception. This is not merely a presumption that permanent residence was abandoned.
A reentry permit, requested through Form I-131, can help a permanent resident seek admission after extended travel. However, it does not automatically preserve continuous residence for naturalization. Form N-470 is a different application available only to qualifying permanent residents working abroad in specified circumstances.
The 3-year marriage rule
The 3-year marriage rule may apply to a permanent resident who has been married to and living in marital union with the same U.S. citizen spouse for the required period. The spouse generally must have been a U.S. citizen throughout those three years.
The rule is not limited to people who originally received their Green Cards through marriage. What matters is whether the applicant satisfies the naturalization requirements as the spouse of a U.S. citizen.
The applicant must generally demonstrate:
- three years of continuous residence as a permanent resident;
- at least 18 months of physical presence during that period;
- three months of residence in the relevant state or USCIS district;
- a qualifying marriage and marital union;
- good moral character; and
- continued eligibility through the oath ceremony.
Divorce or the end of the qualifying marital union may prevent naturalization under the three-year provision. A temporary physical separation does not receive one automatic outcome in every case, but the applicant must still establish that the required marital union continued.
| Requirement | General rule | Spouse of a U.S. citizen |
|---|---|---|
| Time as permanent resident | 5 years | 3 years |
| Continuous residence | 5-year qualifying period | 3-year qualifying period |
| Physical presence | At least 30 months | At least 18 months |
| Marital union | Not required | Required |
| Local residence | At least 3 months | At least 3 months |
| Early filing | Up to 90 calendar days | Up to 90 calendar days for continuous residence |
The 90-day early filing rule
The 90-day early filing rule allows eligible applicants to submit Form N-400 up to 90 calendar days before completing the continuous-residence requirement.
The provision applies only to the continuous-residence period. Applicants must satisfy the other naturalization requirements when they file, including the applicable marriage and marital-union requirements.
USCIS calculates the window by counting back 90 days from the day before the applicant would first complete the required period. Because filing even one day early can lead to rejection, applicants should use the official USCIS Early Filing Calculator instead of estimating three months on a calendar.
Common mistakes and how to avoid them
Counting time in a temporary status. Time in H-1B, L-1, O-1, TN, F-1 or another nonimmigrant category does not count toward the five-year period.
Using the wrong starting date. The I-130, I-140 or I-485 filing date does not usually start the naturalization clock. Applicants should verify the resident since date and official approval or admission record.
Believing a reentry permit protects naturalization eligibility. A reentry permit addresses return after travel but does not automatically preserve continuous residence for Form N-400.
Treating every six-month trip as an automatic break. An absence of more than six months but less than one year creates a rebuttable presumption. An absence of one year or more ordinarily breaks continuous residence unless an exception applies.
Filing exactly three months early. Ninety calendar days and three calendar months are not always equivalent. The USCIS calculator should determine the first filing date.
Assuming marriage-based residence automatically creates three-year eligibility. The applicant must satisfy the citizenship, marriage and marital-union requirements through the applicable period.
Current fee and processing timeline
As of August 2026, the full Form N-400 fee is:
- $710 when filed online;
- $760 when filed on paper.
There is no separate $85 biometric-services fee. Qualifying applicants may request a reduced paper-filing fee of $380 or a fee waiver.
Processing times vary by case and field office. A universal range of eight to fourteen months should not be used. Applicants should consult the current USCIS processing-time tool using the applicable form and office.
Next steps
- Check the resident since date on the Green Card.
- Determine whether the five-year or three-year provision applies.
- List every international trip with exact departure and return dates.
- Calculate total physical presence in the United States.
- Identify any absence longer than six months.
- Confirm the three-month state or district residence requirement.
- Use the USCIS Early Filing Calculator before submitting Form N-400.
- Seek legal guidance if the record includes extended travel, arrests, tax problems or questions about marital union.

Frequently asked questions
Does time spent on H-1B or another temporary visa count?
No. The qualifying period generally begins when the person becomes a lawful permanent resident. Previous time in a nonimmigrant category does not count toward the five-year requirement.
What happens after a trip longer than six months?
An absence of more than six months but less than one year creates a presumption that continuous residence was interrupted. The applicant may present evidence to rebut it. An absence of one year or more ordinarily breaks continuous residence unless an approved exception applies.
Does a reentry permit preserve continuous residence?
No. A reentry permit can support return to the United States after extended travel, but it does not automatically preserve residence for naturalization. Eligible applicants working abroad in specified circumstances may need Form N-470.
Can Form N-400 be filed exactly 90 days early?
USCIS permits filing up to 90 calendar days before completing the continuous-residence period. Because the calculation is not the same as subtracting three months, applicants should confirm the date with the official calculator.
Can the 3-year rule be used after divorce?
Generally, no. Naturalization under the spouse provision requires the qualifying marriage and marital union to continue through the relevant period. The applicant may still become eligible under the general five-year rule.
