Key points
- Most permanent residents need 5 years of continuous residence; spouses living in marital union with a U.S. citizen need 3 years. Either way, physical presence for at least half of that time.[1][2]
- You may file up to 90 days before you complete the required residence period.[3]
- A trip of more than six months can break continuous residence unless you show you did not abandon your U.S. residence; a trip of one year or more breaks it.[4]
- Good moral character is required for the whole period, and some convictions and false statements are listed bars.[1][5]
- Applicants generally must show basic English and knowledge of U.S. history and government, with exceptions for certain disabilities.[6]
You may be ready to apply for U.S. citizenship if you have been a permanent resident for 5 years, or for 3 years if you have been living in marital union with a U.S. citizen spouse, and during that time you were physically present in the United States for at least half the period, lived in your state or USCIS district for at least three months, and kept good moral character.[1][2] You can file up to 90 days before you reach the 5-year or 3-year mark.[3] If you have any arrest, a trip abroad of more than six months, or a past false statement to the government, talk to a lawyer before you file.
The checklist
- Time as a permanent resident. At least 5 years of continuous residence after becoming a permanent resident, or 3 years if the marriage rule below applies.[1][2]
- Continuous residence. No single trip abroad of one year or more, and an explanation ready for any trip of more than six months.[4]
- Physical presence. Days physically in the United States add up to at least half of the 5-year or 3-year period.[1][2]
- Local residence. At least three months living in the state or USCIS district where you file.[1]
- Staying put after you file. Continuous residence in the United States from the date you apply until you become a citizen.[1]
- Good moral character through the whole required period, with no listed bar.[1][5]
- English and civics. Ability to read, write and speak ordinary English, and knowledge of U.S. history and government, unless a disability exception applies.[6]
- Timing. No more than 90 days before the end of your residence period.[3]
Government filing fees are not repeated here because they change. Check the USCIS fee schedule, Form G-1055, on the day you file.[7]
The 5-year rule and the 3-year rule
| General rule | Spouse of a U.S. citizen | |
|---|---|---|
| Residence as a permanent resident | At least 5 years.[1] | At least 3 years.[2] |
| Physical presence | At least half of the 5 years.[1] | At least half of the 3 years.[2] |
| Marriage | Not relevant. | Living in marital union with the spouse for the 3 years, and the spouse a U.S. citizen for that whole period.[2] |
| State or district | At least three months before filing.[1] | Check the rule with the form instructions or a lawyer before filing. |
| Early filing | Up to 90 days before the period ends.[3] | Up to 90 days before the period ends.[3] |
The 3-year marital-union requirement has an exception for a person who was battered or subjected to extreme cruelty by a U.S. citizen spouse or parent.[2] If that applies to you, VAWA, U visa or asylum explains the related protections.
Counting your time
Start from the date you became a permanent resident.[1] Then list every trip abroad with its dates. Two separate tests use that list:
- Continuous residence: a single absence of more than six months but less than one year breaks it unless you can show you did not abandon your U.S. residence; an absence of one year or more breaks it, with narrow exceptions.[4]
- Physical presence: all your days in the United States during the period must add up to at least half of it.[1]
Many short trips can fail the physical presence test even if no single trip is long. One long trip can break continuous residence even if your total days add up. Check both.
Red flags to clear before you file
A naturalization application puts your whole immigration and personal history in front of USCIS. If any of these apply, talk to a lawyer before filing, not after.
- Any arrest, citation, charge or conviction, anywhere, even if dismissed or sealed. The law lists bars to good moral character, including confinement of 180 days or more after a conviction during the required period and an aggravated felony conviction at any time. It also says a person outside those bars can still be found to lack good moral character for other reasons.[5]
- A past false statement to get an immigration benefit. Giving false testimony to obtain immigration benefits is one of the listed bars.[5]
- Ever claiming to be a U.S. citizen when you were not, for example on a job or voter form. A false claim to citizenship is a serious ground under the immigration law.[8]
- A trip abroad of more than six months during the period.[4]
- Using the 3-year rule while separated or divorced, or before your spouse had been a citizen for the full 3 years.[2]
- Questions about how you got your green card, such as a prior removal order or immigration violations before residence. A prior removal order, for example, has its own legal consequences.[9] Have a lawyer review the history before you ask the government to look at it again.
None of these automatically means you cannot naturalize. They mean the answer depends on details that should be checked first.
Keep your record clean while you wait
- Report any move to USCIS within 10 days.[10]
- Keep living in the United States after you file: continuous residence is required from the application until you become a citizen.[1]
- Keep copies of everything you file and every notice you receive.
Why people apply
USCIS lists some of the differences citizenship makes: only citizens can vote in federal elections and serve on federal juries, and a U.S. passport lets you get help from the U.S. government abroad.[11] Visa, green card or citizenship explains how the three kinds of status differ.
Common questions
How early can I apply for citizenship?
A naturalization application may be filed up to 90 days before you complete the required period of residence.[3] Count from the date you became a permanent resident, as shown on your green card, and use the 5-year or 3-year period that applies to you.[1][2]
Does a long trip abroad reset my clock?
It can. An absence of more than six months but less than one year breaks continuous residence unless you show you did not abandon your residence in the United States. An absence of one year or more breaks it, with narrow exceptions.[4] Separately, you need to have been physically present for at least half of the qualifying period.[1]
I am married to a U.S. citizen. Do I qualify after 3 years?
Possibly. The 3-year rule requires that, during those 3 years, you lived in marital union with your spouse, your spouse was a U.S. citizen the whole time, and you were physically present for at least half of it.[2] If you separated, divorced, or your spouse became a citizen partway through, the 5-year rule may apply instead.[1]
I was arrested once, but the case was dismissed. Can I still apply?
Talk to a lawyer before filing. The law lists specific bars to good moral character, such as confinement of 180 days or more after a conviction, and also says a person outside the listed bars can still be found to lack good moral character for other reasons.[5] Bring every court and police record to the consultation.
What does citizenship add to a green card?
USCIS points out that only citizens can vote in federal elections and serve on federal juries, and that a U.S. passport lets you get help from the U.S. government when you are abroad.[11]
