Can I become a US citizen? Check these warning signs first

This page is a quick screen, not a full review of your record. It is general information, not legal advice. Only a lawyer or a DOJ accredited representative can tell you if it is safe for you to apply.

Why check before I apply?

Because the application asks about your whole life, not only the last five years. USCIS runs your fingerprints and an FBI name check, and it reads your old immigration file. Most people pass this with no trouble. But if something in your past makes you deportable, applying can put it in front of an officer.

USCIS says plainly that some problems that block citizenship can also lead to removal (deportation) proceedings. Not everyone who is denied gets sent to immigration court. Still, the safe order is: check first, get advice on any red flag, then file.

Do I meet the basic rules?

Most people apply under the general rules. You must:

• Be 18 or older when you file.
• Have had your green card for 5 years. If you are married to and living with a U.S. citizen who has been a citizen for 3 years, it can be 3 years instead.
• Have lived in the United States without a long break (continuous residence) for those 5 years (or 3), and keep living here until you take the oath.
• Have been physically inside the United States for at least 30 months of the last 5 years (18 months of the last 3 on the marriage path).
• Have lived in your state or USCIS district for at least 3 months before you file.
• Show good moral character for the 5 years (or 3) before you file and up until the oath.
• Pass an English test and a civics test, unless an exception applies.
• Support the principles of the U.S. Constitution.

You can file up to 90 days early, before you reach the 5 or 3 year mark. You still must meet every other rule on the day you file.

English test exceptions. You may take the civics test in your own language with an interpreter if, when you file, you are 50 or older and have had your green card for 20 years, or 55 or older and have had it for 15 years. If you are 65 or older with 20 years as a green card holder, you get a shorter civics test. A disability may excuse you from one or both tests. See Can I skip the English or civics test because of a disability?

What counts as a red flag?

A red flag does not always mean "no." It means "get advice first." Talk to an immigration attorney or a DOJ accredited representative before you file if any of these is true for you.

Your record

• You were ever arrested, cited, detained or charged, anywhere in the world, even if the case was dropped, sealed or expunged. You must report all of it on the form.
• You are on probation, parole or a suspended sentence right now. USCIS will not approve you until it ends.
• You have two or more DUIs, any drug offense, or any conviction for violence, theft or fraud.
• You were ever in jail or prison for a total of 180 days or more.

Your green card and your immigration history

• You are not sure your green card was granted correctly, or you think there was a mistake or a false answer when you got it.
• You were ever in immigration court, deported, or ordered removed.
• You ever said you were a U.S. citizen when you were not, on any form, including a job form or a voter form.
• You ever registered to vote or voted in an election where only citizens may vote. USCIS now says it will send people in this situation to immigration court in most cases.

Time outside the country

• You took any trip of more than 6 months, or you spend long stretches abroad. A trip of 1 year or more breaks your continuous residence. See Will long trips abroad hurt my citizenship application?

Other

• You are a man who lived in the U.S. between ages 18 and 26 and did not register with Selective Service. See Selective Service and citizenship.
• You are behind on child support you were ordered to pay.
• You were born in, or are a citizen of, one of the 39 countries named in the 2025 travel ban proclamations. In late 2025 and early 2026 USCIS put cases like these on hold. A federal court blocked those holds on August 24, 2026, and in an alert dated August 28, 2026 USCIS said it is following that order. Ask a lawyer what this means for you today. See Travel bans: which countries are affected.

What about public benefits and unpaid taxes?

Taxes. The application asks if you ever failed to file a tax return you were required to file, and if you owe taxes. Not filing or not paying can count against your good moral character. If you owe, you can still apply, but bring proof you are fixing it:

• IRS tax transcripts for the last 5 years (3 if you apply through marriage)
• A signed payment agreement with the IRS or your state or local tax office
• Papers that show your payment plan is up to date

USCIS also lists paying overdue taxes in full as a sign that a person has turned things around.

Public benefits. The public charge test is for people applying for a visa, for admission, or for a green card (8 U.S.C. 1182(a)(4)). Applying for citizenship is none of those. California's public charge guide says it does not apply to most immigrants already here, and San Francisco's public charge page says it does not apply to citizenship applications. Using a benefit can actually help you here: proof that you get Medi-Cal, CalFresh, SSI, WIC or similar programs is one way to qualify for a fee waiver. What causes trouble is getting benefits by giving false information, or owing money back. Benefits fraud can count against your good moral character, and USCIS lists paying back an overpayment, such as SSI, as a sign of reform. If you got a letter saying you were overpaid, get advice before you apply. See Will using benefits like CalFresh hurt my immigration case? and Accused of benefits overpayment or welfare fraud.

What does USCIS look at now that it did not before?

Since August 2025, USCIS officers look at your whole life, not only whether you broke a law. They give weight to good things like work history, family care, school, community service and paying taxes. They can also weigh things that are legal but frowned on, such as many traffic tickets. And USCIS may send an officer to talk with your neighbors or coworkers. Read New citizenship rules in 2025 and 2026.

What do I do next?

1. No red flags? Gather your papers with What documents you need, then fill out the form. A free workshop can check it with you.
2. Any red flag? Get your records first, then talk to an attorney or accredited representative. Bring the records to that meeting.
3. Worried about the fee? See How much citizenship costs.

Never pay a notario or consultant for advice on whether you qualify. They are not allowed to give it. See Warning signs of an immigration scam.
