Prism Linguistics provides certified English translation of Mongolian documents in Cyrillic and in the traditional script, and Mongolian interpreters for court, medical and USCIS appointments in Downey and nationwide.
Mongolian Interpreters in Downey
Our Mongolian interpreters in Downey are professional, experienced linguists who work in state courts, law offices, hospitals and USCIS field offices, and who are assigned only after Prism has asked whether the speaker is from Mongolia or from Inner Mongolia.
Khalkha Mongolian is what you will get, and it is usually right. Nearly everyone who comes from Mongolia speaks the Khalkha standard. A Mongolian speaker from Inner Mongolia in China reads the traditional script, may know no Cyrillic, and may prefer Mandarin for anything official, so we ask which country the person came from before assigning a Mongolian interpreter.
The Mongolian interpreter is needed by parents who arrived to join adult children and by newcomers in their first years; it is a recent community, about 50,000 people who identified as Mongolian on 2023 Census Bureau estimates, with the largest numbers in California, Illinois, Virginia, Washington and Colorado. No state runs a court certification exam in Mongolian, so courts use a qualified Mongolian interpreter and come to a private agency like ours for it; we are not a court-appointed vendor. A federally funded hospital must provide a Mongolian interpreter at no cost. At USCIS the interpreter renders the Mongolian answer as given, without correcting or expanding it.
For an in-person assignment in Downey we assign a Mongolian interpreter based in or near the city. Telephone and video interpreting can usually be arranged the same day. We serve courts, attorneys, hospitals, USCIS applicants and private individuals; we are a private agency, not a court-appointed vendor, and we say so up front.
Mongolian Court, Medical and USCIS Interpreters in Downey
Prism Linguistics supplies experienced Mongolian interpreters in Downey for court hearings, depositions, medical appointments and USCIS interviews, in person, by phone or by video, together with certified Mongolian translation of the Cyrillic and dual-script records that accompany those cases.
Downey sits in Los Angeles County, and its cases belong to the Superior Court of California, County of Los Angeles. California merged its municipal courts into the superior court, so no separate city court exists; the Downey Courthouse in the Southeast District hears civil, small claims and traffic matters for Downey, Norwalk and La Mirada, and criminal cases from Downey, La Mirada, Bell, Bell Gardens and South Gate. Courts and attorneys come to Prism for rare languages other providers cannot supply, and for USCIS-compliant certified translation of immigration filings.
Downey Unified School District runs the Global Language Academies of Downey, an English and Spanish dual language immersion program, and provides simultaneous Spanish and sign language interpretation at board meetings. Spanish carries the everyday volume, while immigration filings and hospital appointments call for far rarer languages. That work is coordinated from Prism's New York head office, its only office, with a linguist based near Downey assigned to anything in person.

Mongolian to English Translation Services in Downey
Certified Mongolian to English translation at Prism is done by a qualified Mongolian translator who reads Cyrillic and the traditional script, keeps the field order the document uses and signs a Certificate of Translation Accuracy for every certificate, card and diploma.
Cyrillic, and since 2025 both scripts. Mongolia's civil records, from birth and marriage certificates to the citizen identity card, are issued through the General Authority for State Registration, and since January 2025 state documents carry the traditional Mongolian script alongside Cyrillic. So one Mongolian family's file can mix a 1990s Cyrillic birth certificate with a 2025 dual-script one, and the translator has to read both. Mongolia has been in the Hague Apostille Convention since 2008 and its Ministry of Foreign Affairs apostilles civil registry documents; USCIS does not require the apostille, but some courts do.
Which name is the surname? A Mongolian passport prints the father's name before the given name, and Mongolians are addressed by the given name, so a US form that takes the first word as the first name files the person under the wrong name. Since 2000, identity cards also carry a clan name, the ovog, which older records lack. We transliterate to match the passport, keep the field order the document uses, and add a note saying which element is which. Mongolian Cyrillic has letters Russian lacks, ө and ү, with no single agreed English spelling, so the passport spelling wins.
Every certified Mongolian translation is a complete, word-for-word rendering with a signed Certificate of Translation Accuracy, prepared to meet USCIS requirements. It is done from a clear scan, so a client in Downey gets the same translator, the same price and the same turnaround as one anywhere else in the country.

About the Mongolian Language
Mongolian is the official language of Mongolia, with around 5 million native speakers, plus an additional 6 million speakers in Inner Mongolia (an autonomous region of China). The two communities use different writing systems, Mongolia uses Cyrillic, while Inner Mongolia uses the traditional vertical Mongolian script that descends from Old Uighur. Mongolia is in the middle of a transition back to the traditional script in parallel with Cyrillic. The US Mongolian-American community is around 20,000, concentrated in the Washington DC area, Denver, Chicago, and Los Angeles. Most of our Mongolian translation work is USCIS civil documents and educational transcripts.
Mongolian Interpreting in Downey: FAQs
Can you translate a Mongolian birth certificate written in the traditional script as well as Cyrillic?
Yes. Mongolian documents issued since January 2025 carry both scripts; older ones are Cyrillic alone. We translate every field, stamp and script in full and deliver a signed Certificate of Translation Accuracy prepared for USCIS.
My Mongolian passport lists my father's name first. Which name goes on the translation?
Both, in the order the document uses, with a note saying that the first element is the father's name, the second the given name, and any clan name a separate element. That note is what stops a US clerk filing the record under the wrong surname.
Do you have Mongolian interpreters for a court hearing or deposition?
Yes, in person, by phone or by video. No state certifies court interpreters in Mongolian, so we assign a qualified Mongolian interpreter with legal experience. We are a private agency, not a court-appointed vendor.
Do you have an office in Downey?
No. Our only office is in New York. Mongolian translation is done remotely from a scan, so location makes no difference to the document work. For in-person interpreting in Downey we assign a Mongolian interpreter who is based in or near the city, and phone or video interpreting is available anywhere in the United States.
