Every year, thousands of green card holders submit their N-400 applications without paying an attorney a single dollar. The form is long, yes. It asks a lot of questions. But you don't need to pay an attorney $500 to $2,500 (and often more for a complex case) to fill it out for you.
I'm not going to sugarcoat this though. There are situations where hiring a lawyer is the smart move. And there are situations where it's just throwing money away. This guide will help you figure out which camp you fall into.
For a walkthrough of the N-400 process from start to finish, see our N-400 Guide.
When You Can Skip the Lawyer (and Save Thousands)
If your situation is clean, you don't need a lawyer.
What does "clean" mean? You've been a permanent resident for at least 5 years (or 3 years if married to a U.S. citizen). You've maintained continuous residence and physical presence in the U.S. You've paid your taxes. You have no criminal record beyond maybe a minor traffic ticket. You haven't spent extended periods outside the country.
If that sounds like you, congratulations. There's really no reason to pay attorney fees.
The N-400 form itself is not complicated for someone in this position. It's just long. The questions are pretty basic: where do you live, where have you worked, have you ever been arrested. If you can honestly answer "no" to most of the Part 9 questions about your background, you're in good shape.
The Self-Assessment Checklist
Ask yourself these questions. If you can honestly answer "yes" to all of them, you're probably fine filing on your own:
- Have you been a permanent resident for the required time (5 years, or 3 if married to a U.S. citizen)?
- Have you lived in the U.S. for at least half that time?
- Have you filed taxes every year you were required to?
- Is your record clean beyond minor traffic violations?
- Have all your trips outside the U.S. been under 6 months?
- Did you get your green card through a legitimate process with no misrepresentations?
- Can you read and understand the N-400 questions without confusion?
If you answered "yes" to all of these, you can confidently file without a lawyer.
When You Actually Need a Lawyer
Now for the honest part. There are real situations where legal help isn't optional. Here's when you should seriously consider hiring an immigration attorney:
You have a criminal record. This is the big one. Even arrests that didn't lead to convictions can complicate your case. Certain crimes are "aggravated felonies" that permanently bar you from citizenship. Others might require you to show that enough time has passed. If you've had any run-in with law enforcement beyond a speeding ticket, get a legal opinion before you file. This includes DUIs, which can affect your good moral character determination.
You've had immigration violations. Overstaying a visa, entering without inspection, or any misrepresentation on previous applications can come back to haunt you. A lawyer can help you understand whether these issues will affect your eligibility and how to address them.
You've spent a lot of time outside the U.S. Trips longer than six months can break your continuous residence requirement. Trips of a year or more almost always do. If your travel history is complicated, you need someone who understands the rules around physical presence.
You're genuinely confused by the form. This might sound obvious, but if you're staring at questions and don't understand what they're asking, that's a sign you need help. Mistakes on the N-400 can lead to delays, requests for evidence, or even denials.
You've already been denied. If USCIS rejected your first application, don't just try again without understanding why. A lawyer can review the denial notice and advise whether you can fix the issues or need to wait before reapplying.
You owe back taxes or have child support issues. These won't automatically disqualify you, but they raise questions about your moral character. An attorney can help you document that you're addressing these obligations properly.
Red Flags That Require Legal Consultation
Some situations are serious enough that you should always consult a lawyer before filing:
- Any felony conviction, ever
- Multiple DUIs or a recent DUI (within 5 years)
- Deportation or removal proceedings in your past
- Fraud on any previous immigration application
- Trips abroad of 1 year or longer
- Failure to register for Selective Service (males 18-26)
- Membership in organizations that could raise national security concerns
- Any false claims to U.S. citizenship
If any of these apply to you, an attorney consultation is worth the money. The risk of denial, or worse, being placed in removal proceedings, is too high.
USCIS resumed neighborhood and workplace investigations in 2025, and under guidance issued in August 2026 they now apply to every applicant unless USCIS waives them, which raises the stakes if anything on this list applies to you.
Guided Preparation
Immiva walks you through the application with plain-language questions, builds your completed forms from your answers, and runs automated checks on every answer before you file, always on the form edition USCIS accepts today. A lawyer bills by the hour for that kind of review. Immiva charges a flat fee.
This works well for people who want some hand-holding but don't have complicated legal issues. You still sign the forms and mail them yourself. You're still responsible for the content. But you're not staring at confusing government instructions wondering if you're doing it right.
The cost? Around $199. That's a fraction of what even a basic attorney consultation would run you.
This approach makes sense if:
- You're eligible and want the forms built and checked for you
- You're worried about making small mistakes that cause delays
- You want someone to double-check your work before you submit
- You prefer answering simple questions over decoding government forms
It doesn't make sense if you have red flags in your background that need legal analysis. A guided service can't give you legal advice. If your case involves criminal history, immigration violations, or complex travel patterns, you need an actual attorney.

Making Your Decision: A Simple Framework
Here's how to think about this:
File completely on your own if: You're comfortable with forms and you don't mind doing the research yourself. Just download the form from uscis.gov, follow the instructions, and submit. For details on fees and what to expect, see our N-400 costs breakdown.
Use a guided service if: You want the forms built from your answers and every answer run through automated checks before you file, so a small mistake doesn't slow your case down. The flat fee is a fraction of what an attorney charges.
Hire an attorney if: Your situation involves any of the red flags mentioned above. Criminal history, immigration violations, complex travel, or previous denials all justify the expense. The cost of an attorney is nothing compared to the cost of a denied application or deportation proceedings.
One more thing: USCIS policy moved a lot in 2025, with a new 128-question civics test, a more subjective good moral character review, and resumed background investigations. None of that changes the basics for clean cases.
What Happens After You Decide
Once you've figured out your approach, the process is the same regardless of who helps you:
- Gather your documents. See our N-400 document checklist for what you'll need.
- Complete and submit your application
- Attend your biometrics appointment
- Prepare for your interview and civics test
- Take the oath of citizenship
The whole process typically takes 6-12 months depending on your field office.
