Translation and Interpreting Services in Houston

Prism Language Solutions arranges court, medical and USCIS interpreting in Houston by assigning a linguist who lives in Harris County, and delivers certified translation for the USCIS Houston Field Office on Gears Road and the three Houston immigration courts by email. The company’s only office is in New York. Spanish is the bulk of the work; Vietnamese, Chinese, Arabic, Hindi and Urdu follow; Mam, Q’anjob’al and Swahili are the languages Houston courts and clinics ask an agency to find.

The 2024 American Community Survey has 1.06 million Houstonians aged five and over, 48 percent, speaking a language other than English at home, and 31 percent of the city foreign-born. The city’s own 2021 ACS tabulation counts 795,000 Spanish speakers, then Vietnamese (29,000), Chinese (28,000), Arabic (18,000), Hindi (11,000), French (10,000), Persian (8,000), Tagalog and Urdu (6,000 each). For an in-person job from Katy to Baytown the linguist nearest the address gets the call, and a written confirmation follows within the hour on a business day.

Court Interpreters in Houston

Harris County runs 67 district courts, 24 civil, 29 criminal, 11 family and 3 juvenile, more than any county in Texas. Felonies are heard at the Harris County Criminal Justice Center, 1201 Franklin Street, and larger civil suits at the Civil Courthouse, 201 Caroline Street. Class A and B misdemeanors go to the Harris County Criminal Courts at Law, evictions and small claims to the justice of the peace courts, and Class C misdemeanors and ordinance cases to the Houston Municipal Courts. Fort Bend and Montgomery counties take the suburbs, with district courts in Richmond and Conroe.

Certified Translation for USCIS Houston Field Office

Green card and naturalization interviews for Houston and 30 surrounding counties are held at the Houston Field Office, 810 Gears Road, Suite 100, in the north of the city. The Houston Asylum Office is a few miles away at 16855 Northchase Drive, and its reach is wide: Texas, Oklahoma, New Mexico, Colorado, Utah and Wyoming. At either office the file rule is 8 CFR 103.2(b)(3): a full English translation of every foreign-language document, certified as complete and accurate.

The Houston document set is Mexican and Central American civil records first, then Vietnamese household registration books, Nigerian and Indian certificates, Pakistani NADRA records, Arabic-language documents from Iraq, Syria and Egypt, and Afghan tazkiras from the 2021 arrivals. Vietnamese and Afghan records are the ones most often returned with a request for evidence, usually because a page of stamps or a handwritten tazkira entry was summarized instead of translated. We translate every mark. Turnaround on a birth certificate translation is one business day; the list by form is under USCIS translation.

Immigration Court Interpreters in Houston

Houston has three EOIR immigration courts: 500 Jefferson Street downtown, 8701 South Gessner Road on the southwest side, and 16800 Greenspoint Park Drive in the north. EOIR supplies the hearing interpreter; the attorney supplies the rest, and the rest is where cases are won: the intake, the asylum declaration drafted in the client’s language, the preparation session before an individual hearing. The recurring Houston problem is the respondent booked as a Spanish speaker whose first language is Mam or Q’anjob’al. Guatemalan highland families are a large part of the docket, and a Mam interpreter arranged before the master calendar hearing saves a continuance.

Medical Interpreters for the Texas Medical Center

The Texas Medical Center is the largest medical complex in the world: 21 hospitals and some 10 million patient encounters a year, including Houston Methodist, MD Anderson, Memorial Hermann and Texas Children’s. Harris Health, the county system, runs Ben Taub, a 650-bed Level I trauma center inside the complex, and Lyndon B. Johnson Hospital in the northeast. All provide interpreters at no charge under 45 CFR 92.201, mostly by contracted phone and video. Where the encounter outgrows the line, someone books us: an in-person Vietnamese interpreter for a run of oncology visits at MD Anderson, a Swahili speaker for a refugee family’s first clinic visit. See medical interpreting and medical translation.

Spanish Translation in Houston

Nearly four in ten Houstonians speak Spanish at home, and the Spanish translation work is Mexican, Salvadoran, Honduran and Guatemalan: state civil registry actas, Salvadoran partidas, Guatemalan RENAP certificates, Honduran RNP records. A Spanish interpreter for a Harris County courtroom has to hold the Texas license, keep pace with Central American usage, and know when the witness is a Mayan-language speaker managing in Spanish. Houston ISD, the largest district in Texas with 184,000 students, offers bilingual services in Spanish, Arabic, Vietnamese, Mandarin, Nepali, Urdu and Swahili, which is a fair map of the interpreting demand.

Vietnamese, Arabic and Urdu Interpreters in Houston

Vietnamese is Houston’s second language, concentrated in Midtown, Alief and Bellaire, and a Vietnamese interpreter is a daily booking for clinics, depositions and naturalization interviews; Vietnamese translation is mostly civil records and medical files. Chinese work splits between a Mandarin interpreter for Bellaire and Chinese translation of notarial certificates. An Arabic interpreter serves a community drawn from Iraq, Syria, Egypt and the Gulf, and the dialect matters at the deposition table. Hindi, Urdu and an Urdu interpreter, Telugu, Bengali and Gujarati cover southwest Houston; Farsi, a Dari interpreter and Pashto serve the Afghan arrivals; a Nepali interpreter and a Swahili interpreter serve the refugee corridor along Hillcroft.

Translation for Houston Universities and Refugee Agencies

Texas hosted 97,043 international students in 2024-25, and the University of Houston alone enrolls about 49,000, so diploma translation and transcript translation for admissions are steady work. Interfaith Ministries for Greater Houston, on Main Street, has resettled refugees from more than 40 countries over three decades and took in more Afghans after 2021 than any other local agency. Its caseworkers need Dari, Pashto, Swahili and Burmese interpreters at a day’s notice; phone and video cover most of it (guide rates).
