Ibo is the older spelling; Igbo is how the language writes its own name, and both point at one people from Nigeria's southeast. The clients who ask for an Ibo interpreter are usually the parents and grandparents, because working-age Nigerians conduct their day in English. Our only office is in New York and the interpreters sit wherever the case does, so we assign someone near the courtroom or the clinic for in-person work and connect by phone or video, often the same day, when distance or the calendar makes that the sensible choice. If you have already looked for an Igbo interpreter, this is the same service under the spelling many older records still carry.
The spelling on the booking often hints at the speaker's age. A family that writes Ibo tends to be the older generation, and the older generation is exactly who needs the interpreter, so the request itself tells us something about who will be in the room. Igbo runs to twenty or thirty dialects, and a written standard has sat between them since the early 1970s, but nobody gives a medical history or answers a cross-examination in that standard. Under pressure they fall back toward the speech of home.
So we ask the home town before we assign anyone. The broad split runs between the Onitsha speech of the north and the Owerri speech of the south, and an interpreter from the wrong side of it will follow most of what is said and quietly lose the rest. On a booking that reaches us from any state, matching the interpreter to the speaker's own corner of Igboland is the difference between a record that holds and one that fills the gaps with a guess.
No state runs a court certification exam in Ibo, which is true of most Nigerian languages, so a court works from a qualified Ibo interpreter rather than a certified one, and it is worth telling the clerk that at the outset. Courts, attorneys and law firms come to us directly, often because the language is hard to source at short notice and a hearing will not wait. We say it plainly: we are a private agency, rather than a court-appointed vendor. Give us the court, the case type and the speaker's home town and we confirm what that bench will accept before the date.
A hospital that takes federal money has to provide an Ibo interpreter at no charge to the patient, and most families never hear that this is a right they can ask for. In practice the person who needs one is an elderly parent brought in for a diagnosis, a consent conversation or a discharge plan, where a half-followed sentence can send someone home with the wrong instructions. Video carries a specialist review or a quick follow-up well enough. For a mental health assessment, or when an older patient does better with a person in the room, we send an interpreter in person.
Naturalization and green-card interviews are the everyday work; the asylum interview is where the words carry the most weight. The officer is listening for the applicant's own account, the pauses and the small inconsistencies included, and an interpreter who rounds an answer off or fills a silence has handed over a different story. We brief every Ibo interpreter to render exactly what is said and nothing more, and we never seat a bilingual relative in that chair, however willing they are to help.
Most Nigerian civil records arrive already in English, because the National Population Commission and the High Courts issue them that way, so the certified translation a family actually needs is narrower than they expect. The Ibo turns up around the edges of the file: a handwritten statement from a relative in the village, a traditional marriage record, a letter from a town union or a kindred, an affidavit carrying Ibo place names and kindred titles. Those are the pages we translate, leaving the English record as it stands and spelling every personal name to match the passport. Where a name is written one way on an affidavit and another on the passport, we note the variant so an officer can line the two up. The full document service sits at certified translation.

Our only office is in New York, and our Ibo interpreters work nationwide. For in-person work we assign someone based in or near the city. These are the areas where Ibo 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 an Ibo assignment ever falls short, tell us and we put it right.
