Translation and Interpreting Services in San Francisco

Chinese first, Spanish second: interpreters for the Hall of Justice, SF General and the Concord immigration docket, and certified translation by email.

San Francisco clients get certified translation for any address in the city and interpreters assigned from the Prism Language Solutions network, with a Bay Area linguist sent for in-person work and phone or video used for the rest. Prism has one office, in New York. In this city Chinese, not Spanish, is the most spoken language after English, so Cantonese and Mandarin are the daily bookings here, followed by Spanish, Filipino and Vietnamese.

The numbers explain the staffing. Census one-year estimates for 2024 put 131,407 San Francisco residents in Chinese-speaking homes, 74,357 of whom speak English less than very well, against 89,338 Spanish speakers. Tagalog follows at 24,788 and Vietnamese at 14,043. The five-year birthplace figures show why the Chinese work splits the way it does: 80,490 residents born in mainland China, 13,828 in Hong Kong and 5,546 in Taiwan.

For anyone arranging language support in the city, the first question is therefore not only which language but which variety and which script. A booking that says only "Chinese" will be sent back to you with a question before anything is assigned.

Immigration Court Interpreters After the San Francisco Court Closure

At the close of business on September 4, 2026, the San Francisco Immigration Court closed permanently. More than 115,000 pending cases moved under the Concord Immigration Court at 1855 Gateway Boulevard, which already carried close to 59,000, and the courtrooms at 630 Sansome Street continue only as a hearing location under Concord’s control, with most matters heard in Concord or remotely.

For San Francisco attorneys this changes the logistics, not the work. The hearing interpreter is still the court’s; the declaration, the client preparation sessions and the translated evidence are still counsel’s. What changes is where the client and the interpreter need to be, and whether a preparation session is better held by video before a hearing in Contra Costa County. We place interpreters on either side of the bay. Our translation for immigration attorneys page covers the declaration and exhibit side.

Cantonese and Mandarin Interpreters in San Francisco

A Cantonese interpreter and a Mandarin interpreter are different people, and in San Francisco the difference decides whether a hearing or a clinic visit works. Cantonese and Mandarin are both among the twelve spoken languages California certifies for court interpreting, so a certified interpreter can be sent for either. Tell us where the person grew up. If the client speaks Toishanese or another regional variety, say so at booking.

For documents, Chinese translation follows the record: Traditional characters for material from Hong Kong and Taiwan, Simplified for mainland documents, with names romanized to match the passport rather than re-spelled. Household registers, notarial certificates and school records from the mainland each carry their own seals and formats, and each is translated in full.

Court Interpreters for San Francisco Superior Court

Criminal cases are heard mainly at the Hall of Justice, 850 Bryant Street, with some proceedings at the Civic Center Courthouse, 400 McAllister Street, and the Community Justice Center at 575 Polk Street. Juvenile matters go to 375 Woodside Avenue. The court’s own interpreter division covers courtroom proceedings, and a party asks for one through the clerk; if no interpreter is available, the hearing can be continued.

Outside the courtroom, depositions, mediations and client interviews in Financial District law offices are arranged privately. The federal side sits at the Phillip Burton Federal Building, headquarters of the Northern District of California. More on court interpreting and legal translation.

Certified Translation for the USCIS San Francisco Field Office

San Francisco residents attend adjustment and citizenship interviews at the USCIS San Francisco Field Office, 630 Sansome Street, which also serves Alameda, San Mateo, Marin and other Bay Area and North Coast counties. The San Francisco Asylum Office at 75 Hawthorne Street hears affirmative asylum claims from Northern California, Alaska, Nevada, Oregon and Washington.

Both apply 8 CFR 103.2(b)(3): each foreign-language document needs a complete English translation and a signed statement of the translator’s competence and accuracy. Chinese household registration booklets, Philippine civil registry annotations, Vietnamese birth extracts and Salvadoran and Guatemalan certificates make up most of the San Francisco files we see. The USCIS translation service explains the certificate, and our birth certificate translation keeps every stamp and marginal note.

Medical Interpreters for Zuckerberg San Francisco General

Zuckerberg San Francisco General Hospital on Potrero Avenue is the only Level I trauma center for the 1.5 million people of San Francisco and northern San Mateo County, and it is run by the city’s Department of Public Health as a UCSF teaching hospital. Ninety-two percent of its patients are uninsured or on public coverage. Under 45 CFR 92.201 that language help costs the patient nothing.

Hospitals staff most of this internally. Agency bookings come from clinics, home care and legal settings around the hospital: a Cantonese interpreter for an independent medical examination, a Spanish interpreter for a workers’ compensation deposition about an injury, records translated for a patient moving to care abroad. See medical interpreting.

Filipino, Vietnamese and Spanish Translation for San Francisco Agencies

San Francisco’s Language Access Ordinance requires city departments to translate vital information into its required languages. For years those were Spanish, Chinese and Filipino. Amendments adopted in 2024 lowered the threshold from 10,000 to 6,000 residents with limited English, which brings Vietnamese in as a fourth required language in 2026, and the city’s budget analyst has noted Russian may follow.

That creates steady work for departments, contractors and nonprofits that receive city funds: Tagalog translation for Filipino notices, Vietnamese translation for the new requirement, Spanish translation for community programs, and Russian ahead of any change. Human translators, not machine output, for anything a resident relies on.

Questions we get asked

Where are San Francisco immigration court hearings held now?
Since September 4, 2026 the San Francisco Immigration Court is closed and its cases sit under the Concord Immigration Court at 1855 Gateway Boulevard. The 630 Sansome Street courtrooms remain a hearing location under Concord, and many matters are heard in Concord or remotely. Check the hearing notice.
Do I need a Cantonese or a Mandarin interpreter?
Ask the person which they speak at home and where they grew up. We will not assign a Chinese interpreter until that is answered, because a mismatch wastes the appointment. Certified court interpreters exist in California for both.
Which languages must San Francisco city departments translate into?
Spanish, Chinese and Filipino have been required under the Language Access Ordinance, and 2024 amendments lowering the threshold to 6,000 residents with limited English add Vietnamese in 2026.
Where is the USCIS office for San Francisco?
The San Francisco Field Office is at 630 Sansome Street. Affirmative asylum interviews are held at the San Francisco Asylum Office, 75 Hawthorne Street.
