Looking for the best immigration attorneys in Boston for naturalization and U.S. citizenship cases? This directory narrows the field to three Greater Boston firms that publish a dedicated citizenship practice, and explains what each one is built to handle.
We checked every firm on its own website in October 2026. Each fact below is something the firm states about itself, with a link so you can confirm it before you call.
The short version: Brooks Law Firm leads this list for full-service N-400 help in three languages, with FitzGerald Law Company and Geller Benjamin as strong choices when your file carries a criminal record or a family law issue.
How We Chose and Ranked These Firms
Most green card holders can file Form N-400 on their own. People hire a lawyer when something in the file could cause trouble, so we looked for firms that say plainly how they deal with those problems.
How we ranked them
- A published citizenship practice: a page that covers eligibility, Form N-400 and the interview, not just a line in a list of services.
- Help with complications: long trips abroad, arrests, unpaid taxes, prior filing errors, denials and requests for evidence.
- Access for Boston-area families: offices you can reach, consultation terms and the languages the firm says it works in.
The order follows those three tests. All three firms are reasonable calls, and the best one for you depends on what is in your immigration history.
The 3 Best Immigration Attorneys in Boston for Naturalization
Before comparing firms, it helps to see the road every applicant travels. The graphic below shows the five stages USCIS describes, from the eligibility check to the oath ceremony.
A lawyer adds the most value at the first two stages, before anything is filed. That is where travel gaps, old arrests or tax problems are spotted and documented.
| Firm | Offices | Best For |
|---|---|---|
| #1 Brooks Law Firm | Medford, Framingham | N-400 filings from start to oath, in English, Spanish or Portuguese |
| #2 FitzGerald Law Company | Downtown Boston | Applicants with arrests or convictions, and denied applications |
| #3 Geller Benjamin | Boston, Canton, Woburn | Families whose citizenship case overlaps with divorce or custody |
#1
Brooks Law Firm
Immigration and injury firm in Medford and Framingham with a Boston naturalization practice
Brooks Law Firm is a Massachusetts firm that practices immigration law alongside personal injury and workers’ compensation. Its offices are at 10 High Street in Medford and on Union Avenue in Framingham, and it serves clients across Greater Boston.
Its Boston naturalization page walks through the whole path: eligibility review, Form N-400 and supporting documents, biometrics, the interview and tests, and the oath.
The firm says it works on the hard parts too. That includes travel that may break continuous residence, tax gaps, past visa overstays, criminal record questions, requests for evidence and denials.
Services are offered in English, Spanish and Portuguese, and the contact page offers 100% free consultations. The site also hosts a free immigration form assistant.
Best for: green card holders in Boston and its northern and western suburbs who want one team to take an N-400 from eligibility check to oath ceremony.
#2
FitzGerald Law Company
Downtown Boston firm combining immigration and criminal defense experience
FitzGerald Law Company practices from 185 Devonshire Street in downtown Boston. Its principal attorney is Desmond P. FitzGerald, and the firm cites more than 30 years of immigration and criminal defense experience.
That mix matters for applicants with an arrest or conviction. The firm’s citizenship and naturalization page covers good moral character issues such as unpaid taxes, child support and probation.
It also handles Form N-336 hearing requests after a denial and Form N-600 certificates for people who acquired citizenship through a parent. The team describes itself as multicultural and multilingual, with a Spanish-language site.
Best for: applicants whose record includes criminal charges, or whose N-400 was already denied or stalled.
#3
Geller Benjamin, LLP
Boston immigration and family law firm with offices in Boston, Canton and Woburn
Geller Benjamin, LLP has its Boston office at 69 Canal Street, with more offices in Canton and Woburn. The founding attorneys are Jacob D. Geller and James Benjamin.
The firm’s Boston citizenship page sets out the basic eligibility rules and flags risk factors, such as a criminal history, that need special attention before filing.
Beyond immigration, the firm practices family law, including divorce, custody and support, along with bankruptcy and real estate. That can help when a divorce, a child support order or a marriage-based timeline affects the citizenship application.
Best for: applicants south or north of the city, and families whose naturalization question is tied to a family court matter.
What Naturalization Requires in 2026
The core rules are federal, so they are the same in Boston as anywhere else. These are the points that most often decide whether an application is ready.
- Time as a permanent resident. Generally five years under 8 U.S.C. 1427(a), or three years if you are married to and living with a U.S. citizen spouse under 8 U.S.C. 1430(a).
- Physical presence and local residence. You must have been in the U.S. for at least half of that period and lived in Massachusetts, or your USCIS district, for three months before filing.
- Early filing. The USCIS Form N-400 page allows filing 90 calendar days before you complete the residence period.
- Long trips abroad. An absence of more than six months but less than a year presumes a break in continuous residence, which you can try to rebut. A trip of a year or more breaks it.
- Good moral character. USCIS asks for arrest and court records, proof of tax filing or a payment plan, and child support records where they apply.
The interview includes an English test and a civics test. Under the USCIS study guidance, anyone who filed on or after October 20, 2025 takes the 2025 civics test: 20 questions from a list of 128, with 12 correct answers needed.
Some applicants are exempt from the English test because of age and years of residence, under the 50/20 and 55/15 rules in 8 CFR 312.1(b). Applicants 65 or older with 20 years of residence get a shorter civics test.
If you fail a test, USCIS retests you on that part 60 to 90 days after the first interview. Filing fees change, so check the current amount on the USCIS fee schedule before you pay.
If USCIS Denies or Delays Your Application
You can ask for a hearing within 30 days of receiving the denial, under 8 CFR 336.2. That request is made on Form N-336, and USCIS must schedule the hearing within 180 days of the filing.
If USCIS makes no decision within 120 days after your interview, 8 U.S.C. 1447(b) lets you ask the federal district court where you live to hear the case. Whether that step makes sense depends on the facts of your file.

How to Choose the Right Citizenship Lawyer
Start with your file, not the firm. If your history is clean, you mainly need careful paperwork and interview preparation. If it includes arrests, long trips or past immigration problems, look for a firm that explains how it handles them.
Then ask every firm the same questions:
- Will a lawyer review my full immigration and travel history before we file?
- Is the fee flat, and does it include the interview and any request for evidence?
- Who will attend the interview with me at the USCIS office?
- Can we work in my language, and can we meet by video?
Treat any promise of guaranteed approval as a red flag. USCIS decides each case, and no lawyer can promise the result.
