USCIS Los Angeles Field Office

Two speeds at one office

The Los Angeles Field Office is slow on naturalization and fast on green cards, judging by USCIS’s own counts for April to June 2026.

Sources: USCIS N-400 and I-485 performance data by field office, FY2026 Q3 (April 1 to June 30, 2026).

The office took in 2,502 civilian N-400s and decided 529. On the employment side it approved 748 more I-485s than it received; by our count, that was the third-largest gap of that kind among 93 field offices. A quarter’s approvals can include cases filed in earlier quarters. The two offices ahead of it were San Fernando Valley and Los Angeles County, also in the Los Angeles area.

For military N-400s (applicants whose eligibility rests on U.S. armed forces service), USCIS reported 41 pending and withheld the received, approved and denied counts: we show those as not reported. Across all N-400s the office received 2,509, approved 437, denied 101 and had 11,703 pending. Across all I-485 categories it received 4,557, approved 4,608, denied 278 and had 20,529 pending. That includes 6,652 humanitarian cases (asylees, refugees, Indochinese and Cuban refugees), of which 502 were decided in the quarter.

Our backlog ratio, and the national medians

We divide pending cases by cases decided (approved plus denied) in the quarter. It is our rough indicator from USCIS counts, not a USCIS processing time, so do not read it as months. A higher number means a longer line relative to how fast the office was deciding. Figures are rounded to one decimal.

The middle column sums the 93 field office rows in the same files; for the N-400, seven offices had denials withheld, so it runs slightly high. The national medians are months from receipt to completion for cases USCIS finished nationwide in April to June 2026 (All Forms by Quarter, FY2026 Q3). In our ranking of the 83 field offices with both N-400 approvals and denials reported, Los Angeles had the 13th-highest N-400 ratio.

Which Los Angeles office has your case

This is easy to miss. USCIS lists two separate field offices, Los Angeles and Los Angeles County, and its locator gives both the same address: 300 North Los Angeles Street, Los Angeles, CA 90012 (locator data, Aug 28, 2026 file). Your ZIP code decides which one handles you. In the locator, 90012, 90001, 90210 (Beverly Hills) and 91601 (North Hollywood) go to Los Angeles; 90802 (Long Beach) and 90650 (Norwalk) go to Los Angeles County.

Within Los Angeles County, the locator splits active ZIP codes like this: 217 to Los Angeles, 177 to Los Angeles County and 103 to San Fernando Valley. Los Angeles takes most of the city plus Pasadena, Glendale, Burbank, Santa Monica and Beverly Hills. Los Angeles County takes Long Beach, Inglewood, Torrance, Whittier, Compton, Carson and much of the southeast.

Five offices serve the wider area, and their numbers differ:

Ratios: our rough indicator from the same USCIS files, civilian N-400 and all I-485 categories, April to June 2026. The locator assigns your ZIP to one office; you don’t choose. USCIS also says it may move work between field offices, so an interview or evidence notice can come from an office that never handled your case. Biometrics still go to the closest application support center (USCIS Field Offices). Always use the address on your notice.

Getting in: appointments, interviews, ceremonies

No one walks in. A visit starts with either a USCIS notice or an appointment you request.

• Interviews. For an N-400, USCIS schedules the interview once its preliminary steps are done (10 Steps to Naturalization). For an I-485, USCIS decides whether an interview is needed; the notice gives the date, time and place (adjustment of status).
• Appointments you request. The Contact Center says in-person appointments are for services that cannot be done by phone, mail or email: emergency travel documents, proof of status to work or travel, or permanent residence granted by an Immigration Judge. Use the online request or call 800-375-5283 (TTY 800-767-1833). If you were looking for InfoPass, these two channels are how USCIS takes appointment requests today.
• Oath ceremonies. USCIS does not publish a ceremony venue for this office. The oath may be the same day as the interview, or Form N-445 arrives with the date, time and location (naturalization ceremonies).

USCIS does not post visiting hours for the Los Angeles office on uscis.gov; your notice gives the time. If you are ill, USCIS asks you to cancel and reschedule rather than come in, without penalty.

When your Los Angeles N-400 seems stuck

The office had 11,662 civilian N-400s pending and decided 529 in one quarter. If yours is one of them:

1. Look up the current range for the N-400 at the Los Angeles office on the USCIS processing times page. USCIS does not research cases still inside that range.
2. Once you are outside it, file a case inquiry through e-Request.
3. If you have an urgent reason, check the expedite criteria; the decision is at USCIS’s discretion.
4. Keep your address current so the interview notice finds you.

The YourCaseStatus app (coming soon) will alert you when your status changes.
