You don’t need an immigration lawyer to apply for U.S. citizenship if your record is clean and your immigration history is straightforward, but you probably do need one if there’s a past arrest, a long trip abroad, any marijuana involvement, immigration violations, tax problems, or a marriage-based green card from a marriage that has since ended. The naturalization process is designed for ordinary applicants to handle themselves, and the government filing fee alone runs $710 to $760. Where a lawyer earns the fee is in complicated cases, because filing for citizenship invites U.S. Citizenship and Immigration Services (USCIS) to review your entire immigration record. If that review turns up problems, the agency doesn’t just deny the application. It can refer you to removal proceedings and put your green card at risk.
When You Can Likely File on Your Own
You’re a good candidate to file without a lawyer if all of the following are true:
- You’ve held your green card and lived continuously in the U.S. for at least five years, or three years if you’re married to a U.S. citizen, with no trips abroad longer than six months.
- You’ve been physically present in the U.S. for at least 30 months of the past five years, or 18 months of the past three years for spouses of U.S. citizens.1U.S. Citizenship and Immigration Services. Continuous Residence and Physical Presence Requirements for Naturalization
- You’ve never been arrested, charged, or convicted of any crime.
- You obtained your green card without issues and have never been in removal proceedings or misrepresented facts on an immigration application.
- You’ve consistently filed federal and state tax returns and don’t owe back taxes.
If those all check out, the application is largely a matter of filling out Form N-400 carefully, gathering documents, and preparing for the interview. USCIS publishes study materials for the civics and English tests, and the form itself comes with straightforward instructions.2U.S. Citizenship and Immigration Services.

When You Should Hire a Lawyer
Certain facts in your history turn a routine application into a legal risk. In these situations, a lawyer’s real job is to assess the danger before you file, not after.
Any Criminal History
This is the most common reason to get legal advice, and the bar is lower than people expect. Any arrest matters to USCIS, even one that didn’t lead to a conviction, was dismissed, or was expunged. You’re required to disclose your full criminal history on Form N-400, and USCIS runs its own background checks. Failing to disclose is treated as misrepresentation, which can independently sink the application.3eCFR. 8 CFR 316.10 – Good Moral Character
Some offenses create a conditional bar to good moral character during the statutory period, typically the five years before filing. Those include crimes involving moral turpitude, any controlled substance violation, providing false testimony, and being incarcerated for 180 days or more. Other convictions are permanent bars with no workaround: a murder conviction at any time, or an aggravated felony conviction on or after November 29, 1990, permanently disqualifies you from establishing good moral character for naturalization.4U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part F Chapter 4 – Permanent Bars to Good Moral Character
A lawyer can tell you which offenses USCIS will flag, whether they fall within the statutory period, and whether filing would expose you to removal rather than just a denial.
Marijuana Use or Employment
This trips up applicants in states where marijuana is legal. Federal law still classifies marijuana as a Schedule I controlled substance, and USCIS has confirmed that any marijuana-related activity is a conditional bar to good moral character even when it was legal under state law. That covers recreational use, medical use with a prescription, and working in the cannabis industry. If any of that applies to you during the statutory period, get legal advice before filing.5U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part F – Good Moral Character
Immigration Violations
Overstaying a visa before getting your green card, entering without inspection, or misrepresenting facts on a prior immigration application all raise questions about the validity of your permanent residence itself. These are the cases where naturalization can backfire. USCIS may conclude the green card should never have been issued and initiate removal. A lawyer should review your full history before you invite that scrutiny.
Long Absences From the United States
Any absence longer than six months during the statutory period creates a legal presumption that you broke the continuity of your residence. You can rebut it with evidence you kept your U.S. ties, but the burden is on you. An absence of a year or more is treated more seriously and can raise the separate question of whether you abandoned permanent resident status entirely.6U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part D Chapter 3 – Continuous Residence
A lawyer can help you gather the right evidence or advise you to wait until the trip falls outside the statutory window.
Selective Service Issues
Males who lived in the U.S. between ages 18 and 26 were generally required to register with the Selective Service. Failing to register can block naturalization if USCIS finds the failure was knowing and willful. Applicants between 26 and 31 face the toughest scrutiny, because the failure is recent enough to fall within or near the statutory period but they can no longer register. Applicants over 31 are generally in the clear, because the failure falls outside the statutory period. If you’re unsure whether you registered, a lawyer can help you request a status information letter and build the case that any failure wasn’t intentional.7U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part D Chapter 7 – Attachment to the Constitution
Marriage-Based Green Card, Marriage Now Ended
If you got your green card through marriage and that marriage has since ended, expect extra scrutiny of whether the marriage was genuine. Multiple marriages or divorces during the statutory period can also raise good moral character questions. A lawyer can help you compile documentation showing the legitimacy of the original marriage and address inconsistencies before USCIS finds them.
Tax Problems
Unfiled returns or unpaid back taxes can be treated as a failure of good moral character. You’ll want to get current before filing, and a lawyer or tax professional can advise on the sequence.
What a Lawyer Actually Does
The most important work happens before any form is filed. A lawyer reviews your complete history and tells you whether applying is safe. For someone with a complicated background, that analysis is the whole point. It’s the difference between filing confidently and gambling with your green card.
After that, the lawyer prepares and reviews your Form N-400 and supporting documents to make sure every answer is accurate and consistent, since incomplete or contradictory answers are a common source of delays and requests for evidence. The lawyer also prepares you for the USCIS interview and can attend it with you, which matters most when the officer is likely to press on criminal history, travel, or a prior marriage.
What It Costs
The N-400 filing fee is $710 if you file online and $760 by mail. A reduced fee of $380 is available for applicants who qualify. The fee is not refundable if your application is denied.2U.S. Citizenship and Immigration Services. N-400, Application for Naturalization
If paying the fee would be a hardship, you can request a full fee waiver on Form I-912. You qualify if you receive a means-tested benefit like Medicaid, SNAP, TANF, or SSI; if your household income is at or below 150 percent of the Federal Poverty Guidelines; or if you face a specific hardship such as a medical emergency, unemployment, or homelessness.8U.S. Citizenship and Immigration Services. Form I-912 Instructions for Request for Fee Waiver
Immigration attorneys typically charge a flat fee for naturalization. A straightforward case usually runs about $1,000 to $1,500, sometimes more depending on your location and whether interview attendance is included. Cases with criminal history, immigration violations, or other complications cost more because the analysis is heavier. Many immigration attorneys offer free or low-cost initial consultations, so you can get a preliminary read on whether you even need representation before committing to the expense.
If Your Application Is Denied
A denial isn’t necessarily the end, but the deadlines are tight. You can request an administrative hearing by filing Form N-336 within 30 calendar days of receiving the denial notice, or 33 days if it was mailed to you. A different USCIS officer reviews the decision at the hearing. Miss that window and you generally lose the right to it.9U.S. Citizenship and Immigration Services. N-336, Request for a Hearing on a Decision in Naturalization Proceedings
If the hearing doesn’t go your way, you can seek judicial review in the federal district court where you live. The court conducts its own independent review of the facts and law, so it’s a meaningful second chance rather than a rubber stamp.10Office of the Law Revision Counsel. 8 USC 1421 – Naturalization Authority
This is where a lawyer matters most. The appeals process turns on legal arguments and evidence standards that are hard to handle alone, and the deadlines leave no room for error.
Finding Legitimate Help
You don’t have to hire an expensive private attorney. The Department of Justice accredits non-attorney representatives who work through recognized nonprofit organizations. They’re authorized to handle immigration cases before USCIS and the immigration courts and often work for free or at reduced cost. The DOJ’s Recognition and Accreditation Program was created to expand access to legal help for people who can’t afford a private lawyer.11United States Department of Justice. Recognition and Accreditation Program
If you’d rather hire privately, the American Immigration Lawyers Association keeps a searchable directory of immigration attorneys, and your state bar can also refer you. Ask any lawyer specifically about their experience with naturalization cases like yours. Someone who mostly handles business immigration may not be the right fit for a case involving a criminal record.
One warning: people who call themselves “notarios” or “immigration consultants” are not authorized to give legal advice in the United States. In many Latin American countries, a “notario” is a trained legal professional, but that title carries no legal authority here. USCIS specifically warns against using these services, and the DOJ has confirmed they are breaking the law if they give legal advice or represent you.12U.S. Citizenship and Immigration Services.
