Where the citizenship interview happens for Gulfport residents
There is no USCIS field office in Mississippi, so a Gulfport naturalization case is handled by the USCIS New Orleans Field Office, 1250 Poydras Street, Suite 1800, New Orleans, LA 70113. The N-400 is filed online or by mail. USCIS often reuses fingerprints already on file; when it does not, the biometrics notice for Gulf Coast applicants is commonly set at the New Orleans Application Support Center in the same building, and the notice controls. The interview comes next, in New Orleans, about 80 miles from Gulfport. The officer reviews the application line by line, tests English reading, writing and speaking, asks the civics questions, and then reviews the whole file: how you got your green card, every trip outside the country, taxes, child support and any arrest. If approved, USCIS schedules the oath ceremony and the notice tells you where and when. To get there, an applicant needs:
- Five years as a permanent resident, or three years if you have been married to and living with a U.S. citizen for that time
- Physical presence in the United States for at least half of that period, with no single trip of six months or more that broke continuous residence
- Residence in Mississippi for at least three months before filing, so the case lands at the New Orleans office
- Good moral character for the statutory period, which is where arrests, unpaid taxes and child support come up
- English and civics, with exceptions for applicants over 50 with 20 years of residence or over 55 with 15 years, who may test in Spanish, and a medical waiver for disability
Military service is its own route. Airmen at Keesler Air Force Base in Biloxi and sailors and Seabees at the Naval Construction Battalion Center in Gulfport can naturalize under the military provisions of the immigration law. A service member with at least one year of honorable service can apply without the five-year residence requirement, and anyone who has served honorably during a designated period of hostilities, which has been continuous since September 11, 2001, can apply with any length of service and without even holding a green card first. The application needs a certified Form N-426 from the service member's command, and the filing fee is waived for military applicants. The Jackson Application Support Center takes military personnel without an appointment, and our office coordinates with the base legal office when the command's certification is slow. Spouses of service members about to deploy or be stationed abroad have their own expedited provision.
At the Gulfport office we review your immigration history and your travel, tax and criminal records before anything is filed, prepare the N-400 and the supporting documents, and file it. We track the case, prepare you for the English and civics tests with practice materials in the language you prefer, and attend the interview with you in New Orleans. On our review date, the field offices USCIS lists were completing 80 percent of N-400s within roughly 10 to 13 months, and New Orleans posts its own figure on the USCIS processing-times page. Military families facing a permanent change of station mid-case can usually keep the application moving by transferring it to the new office. Consultations at 1617 25th Ave are available in English and Spanish.

We prepare the N-400 and the supporting documents, including the N-426 certification for service members, and file it online or by mail with USCIS.
Biometrics and tracking
We prepare you for the biometrics appointment if USCIS schedules one, usually at the New Orleans ASC, and monitor the case for requests for evidence.

Questions from Gulfport clients
Where is the citizenship interview for Gulfport residents?
At the USCIS New Orleans Field Office, 1250 Poydras Street, Suite 1800, New Orleans, LA 70113, about 80 miles from Gulfport. USCIS assigns Gulfport, Biloxi and the rest of the coast to that office because Mississippi has no field office of its own. Your interview notice confirms the address and time.
How long does citizenship take in Gulfport, MS?
Plan on roughly a year from filing to interview. On our review date the field offices USCIS lists were completing 80 percent of N-400s within about 10 to 13 months, and the New Orleans office posts its own figure on the USCIS processing-times page. Military applications are often faster.
How much does a citizenship lawyer cost in Gulfport?
Consultations with our Gulfport office are available in person, by phone or by video, in English and Spanish, and fees are discussed at the consultation.
Can I become a citizen through the military at Keesler or NCBC Gulfport?
Yes. One year of honorable service qualifies you without the five-year residence requirement, and any honorable service during the period of hostilities that has run since September 11, 2001 qualifies you without a green card at all. You need a certified N-426 from your command, and the filing fee is waived for military applicants.
Do I need a lawyer for my naturalization interview in New Orleans?
Most applicants with a clean record and straightforward history do not. Anyone with an arrest, a trip abroad of six months or more, unfiled taxes, unpaid child support, or a green card obtained through a marriage that later ended should have the file reviewed first, because the interview can reopen the green card itself. We attend the interview with clients who want us there.
Can I take the citizenship test in Spanish?
Only if you are over 50 and have been a permanent resident for at least 20 years, or over 55 with at least 15 years. In that case the civics test is given in Spanish through an interpreter and the English test is waived. A physical or developmental disability that prevents learning can also be the basis for a medical waiver on Form N-648.
Where do I go for fingerprints for my N-400 on the Gulf Coast?
USCIS often reuses the fingerprints from your green card case. If it schedules a new appointment, Gulf Coast applicants are commonly sent to the New Orleans Application Support Center, 1250 Poydras Street, 18th Floor, Suite 1800, though some notices name the Jackson ASC. Follow the notice. Military personnel can walk in at the Jackson ASC between 9 a.m. and 3 p.m.
What if I have an arrest on my record?
Bring the certified court disposition to the consultation before anything is filed. Many arrests and minor convictions do not bar citizenship, but some do, and a few make a permanent resident removable. We review the record, decide whether and when to file, and present the disposition properly at the interview.
Will my children become citizens when I do?
Children under 18 who are permanent residents and live in your legal and physical custody become citizens automatically when you take the oath. They do not take a test; they get proof of citizenship through a U.S. passport or a certificate of citizenship on Form N-600, which we prepare for them.
I am getting orders to another base before my interview. What happens to my case?
Tell us as soon as you have the orders. USCIS can transfer a pending N-400 to the field office near the new duty station, and the application does not have to be refiled. Spouses with pending applications of their own can usually be transferred the same way.
