For the Shanghai-born patient or witness who does not follow Mandarin: a real Shanghainese interpreter in the hospital, the courtroom or the USCIS office, wherever in the US that is.
Prism Linguistics provides Shanghainese interpreters for hospital and nursing home appointments, court hearings, depositions and USCIS interviews anywhere in the United States, in person, by phone or by video, for the older Shanghai-born speakers a Mandarin interpreter cannot serve, together with certified English translation of the Standard Chinese documents their families file.

Almost every request for a Shanghainese interpreter begins with someone having tried Mandarin first. The hospital booked its usual Chinese interpreter, the grandmother nodded politely, and afterwards the family realised she had understood a fraction of it. That is the moment we get the call. Our office is in New York and the interpreters are spread across the country; because most of them are themselves older, we are frank about when in-person is possible and when video is the faster answer.
Shanghainese belongs to the Wu group and has something like 14 million speakers, yet it shares no mutual intelligibility with Mandarin: the sounds, the pronouns and much of the everyday vocabulary are different. In the US its speakers are a specific generation. They are people who left Shanghai when the city still ran on Shanghainese, now in their seventies and eighties, and the parents who came later to live with adult children in Queens, the San Gabriel Valley or the Bay Area. Their grandchildren speak English and, at best, Mandarin.
Ask first whether Mandarin is an option at all. Some Shanghai natives follow Mandarin comfortably and a Mandarin interpreter can be found within the hour. Others, particularly the very old and anyone who is unwell or frightened, revert to the language of their childhood and lose the thread in anything else. The supply side is thin, and honestly so: Shanghai itself has watched the language fade among its young, so the pool of interpreters able to work in it is small and mostly older. We say that at intake so nobody plans around a linguist who does not exist.
Medical work is the bulk of it: an oncology consultation, a rehab assessment in a nursing facility, a home health intake, a conversation about a feeding tube. Any hospital or facility that takes federal funding has to provide a Shanghainese interpreter at no cost to the patient, and the family should say the word Shanghainese, not Chinese, when they ask. What usually goes wrong is the adult child in the room who softens the prognosis on the way through. We ask that they sit beside the patient and let the interpreter do the rendering. Video reaches a bedside in an hour; for capacity assessments and end-of-life discussions we look for someone to attend in person.
No state runs a certification exam in Shanghainese, so a court will accept a registered or otherwise qualified interpreter, and it will almost never have one on its roster. This is one of the rare languages courts have come to Prism for. The cases are what you would expect for that age group: elder financial abuse, guardianship, a landlord dispute over a Chinatown apartment, a witness in a family business quarrel who gave every relevant instruction in Shanghainese. Tell us the court and the case type and we confirm what the judge will accept before the date. We are a private agency, not a court-appointed vendor.
At USCIS the typical Shanghainese applicant is a parent sponsored by a citizen child, either at a green card interview or at naturalization under the age-based exemption from the English test, where the civics questions are put through an interpreter. The officer wants the applicant's own answers, in full, without the daughter leaning in to explain. We brief the interpreter to render only what is said. If the applicant is comfortable in Mandarin we will say so and book that instead, since it is easier to schedule; if not, we hold out for Shanghainese, because a misunderstood question at a naturalization interview is not easily undone.
Nothing official from Shanghai is written in Shanghainese. The birth notarial certificate, the household register, the marriage certificate, the police clearance and the university diploma are all in Standard Chinese, and we translate them as Chinese: full text, notary office name and seal included, with the pinyin name matched to the passport. USCIS normally expects the notarial birth certificate rather than a hospital record, and a family that sends only the hospital slip gets a request for evidence. Where Shanghainese itself has to be put on paper is a recording: a voicemail from a relative, a phone call that became evidence, a deposition or statement given in the family's own language. The language has no settled written form, so a Shanghai-born linguist listens, writes the content in Chinese characters with the Shanghainese wording marked, translates it and signs the transcript. A Mandarin-speaking transcriber will mishear it and not know that they have. The document service is at certified translation.
Tell us the date, the city and the setting, or send a clear scan of the document. We reply with a fixed price and, for interpreting, a named linguist. Call +1 (833) 282 8883, email info@prismlinguistics.com, or use the quote form and you will hear back within 60 minutes during business hours.
Our only office is in New York, and our Shanghainese interpreters work nationwide. For in-person work we assign someone based in or near the city. These are the areas where Shanghainese work is concentrated; the full list of 288 cities is below it.
Prism Linguistics is rated 4.6 out of 5 across 67 client reviews for its interpreting and translation work in the United States. That is the company-wide figure; we do not publish a separate rating per language because there is no honest way to measure one. If a Shanghainese assignment ever falls short, tell us and we put it right.
