Krio is a language in its own right, not broken English, and Sierra Leone's paperwork is in English; we interpret for asylum, court and USCIS and translate the Krio inside a file.
Prism Linguistics provides Krio interpreters for asylum interviews, immigration court and USCIS appointments across the United States, with a strong base in the DC and Maryland Sierra Leonean community, and certified translation of any Krio writing in a case file.

Krio is the English-based creole that most of Sierra Leone speaks, and the recurring error is to hear it as broken English and hand the speaker an English interpreter. It has its own grammar and a vocabulary drawn from English, Yoruba, Igbo and more, and a Sierra Leonean at ease in daily English can still lose the thread of a cross-examination. Our office is in New York and our Krio interpreters work nationwide, with the largest Sierra Leonean community clustered around Washington and the Maryland suburbs. The person who truly needs a Krio interpreter is usually older, only recently arrived, or facing an asylum interview where the exact words matter.
The American Community Survey counts roughly 34,000 people born in Sierra Leone living in the United States, and the largest concentration is in the Washington metro, especially the Maryland suburbs of Prince George's and Montgomery counties. Many are comfortable in English for ordinary life. The trouble comes in the settings that turn on precise wording, where treating Krio as an accent of English produces answers that do not mean what the speaker intended.
Ask the person, do not assume. Someone who handles a benefits call in English may not follow a judge's questions or a doctor's explanation, and pride can keep them from saying so. For court, asylum and medical work we assign a Krio interpreter rather than let English stand in, often by phone or video because in-person interpreters are spread thin.
No state runs a court certification exam in Krio, so a court works from a registered or otherwise qualified Krio interpreter, often over phone or video, and Krio is one of the rare languages a court reaches outside its own roster to fill. A Krio speaker who seems to be following the proceedings in English can still miss the difference between two similar questions, which is exactly where a case is won or lost. Tell us the court and the case type and we confirm what the bench will accept. As a private agency, we are not on any court's appointed-vendor list.
Asylum is the heart of Krio interpreting. A claim often rests entirely on the applicant's own telling of what happened, and the officer weighs the wording, the order of events and the hesitations. An interpreter who renders the gist rather than the words, or quietly cleans up a painful account, changes the evidence in front of the officer. We brief every interpreter to carry each answer across whole, and we never let a friend or a relative interpret at an asylum interview.
Beyond asylum, most Krio USCIS work is the naturalization test and adjustment-of-status interviews. The standard is the same in every chair: the interpreter renders what was said and nothing more, and no bilingual relative sits in. For a remote appointment we use video so the interpreter can read the applicant rather than work from an audio-only line. Tell us the interview type and the date and we place a Krio interpreter to match.
Krio translation is a narrower job than most, because Sierra Leone's records are in English.
Sierra Leone's official language is English, so a birth or death certificate is already in English and needs no translation. Those certificates come from the National Civil Registration Authority, which issues securitised, serially numbered documents tied to a National Identification Number; anyone born before the NCRA existed holds an older record from the births and deaths registry, or none at all. According to the State Department's reciprocity notes, fraud in the civil registry there is common, so the translator's task is to reproduce a document exactly, its seals, serial numbers and handwritten corrections and all, without tidying anything. What we do translate is the Krio inside a file: a witness statement, a text message put in as an exhibit, a letter from a relative. A reader who treats Krio as broken English gets the meaning wrong, so we render it as Krio, with a signed Certificate of Translation Accuracy prepared to meet USCIS requirements. The full 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 Krio interpreters work nationwide. For in-person work we assign someone based in or near the city. These are the areas where Krio 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 Krio assignment ever falls short, tell us and we put it right.
