Last reviewed August 24, 2026 by the Prism Linguistics editorial team
Prism Linguistics provides legal interpreting services across the United States: court interpreters for state, federal, and EOIR immigration courts, plus depositions, attorney-client meetings, mediations, and jail visits, in 326 languages. Interpreters are court-experienced, background-checked, and certified where the setting requires it, with 24/7 scheduling and quotes returned within 60 minutes during business hours.
An interpreter error on the record is not a small thing. It can draw an objection, a motion, or in the worst case an appeal, and it always costs time nobody billed for. So we treat legal work as its own discipline, staffed by interpreters who know what a clean record requires, not just what the words mean.
Courtroom work is the core of this page. We place court interpreters in state and county courts for criminal and civil calendars, in US federal district courts, and in EOIR immigration courts, where a removal hearing may turn entirely on how precisely testimony crosses the language barrier.
A hearing is not a conversation. The register has to hold: what counsel puts to a witness is interpreted as counsel put it, not softened, not summarized, not explained. Our interpreters know the difference between interpreting for the record and helping someone follow along, and they know which one the judge expects at any given moment. Where the bench or opposing counsel wants the interpreter's qualifications on the record, we provide them in writing before the date.
Calendars slip, cases go part-heard, and afternoon lists run long. Give us the scheduled time and a realistic finish and we book to that, and we tell you up front when a language will be hard to place for a particular date rather than letting you find out at the courthouse.
Most of a matter happens outside the courtroom. These are the settings we staff most often for US attorneys.
Criminal and civil calendars in state, county, and federal courts, plus EOIR immigration hearings, with interpreters whose credentials stand up to scrutiny from the bench.
Sworn testimony at law firms and court reporters’ offices, keeping a clean record through exhibits, objections, and read-backs, on-site or by video.
Prep sessions before testimony, so the witness understands the questions coming and counsel understands the answers, before either is on the record.
Taking instructions, reviewing statements line by line, explaining a plea offer or a settlement. The meetings where a client either tells you everything or nothing.
Private dispute resolution where tone matters as much as terms, staffed with interpreters experienced in commercial and family matters alike.
Attorney visits in county jails, federal facilities, and ICE detention centers, with interpreters cleared for the facility's visitation procedures.
Police interview rooms are a related but separate discipline: interviews under caution, statements, and victim support run through our police interpreting services.
Anyone bilingual can call themselves a legal interpreter, so it helps to know which credentials actually exist in the US before you book anywhere, including with us.
Our own standard: every legal interpreter we place is court-experienced, background-checked, and certified where the setting requires it and the credential exists in that language. We tell you which of those applies to your interpreter before the booking, in writing, so you can put it on the record if asked.
Testimony is almost always consecutive: question, pause, interpretation, answer, interpretation. It is slower, roughly doubling the time on the record, but it is the only mode a court reporter can cleanly capture. Simultaneous interpreting, delivered quietly at the defendant’s or client’s ear, keeps a party following the proceedings in real time without slowing them down; larger multi-party proceedings sometimes borrow equipment-based setups from our conference interpreting services.
| Mode | Used for | Worth knowing |
|---|---|---|
| Consecutive, on-site | Testimony, depositions, client meetings, mediations, jail visits | Budget roughly double the speaking time; see face to face interpreting |
| Simultaneous, whispered | Keeping a defendant or party following proceedings in real time | One listener at a time; equipment needed for more |
| Telephone | Short client updates, urgent after-hours contact, scheduling calls | Connects in minutes, 24/7, via telephone interpreting |

Plenty of matters need paper on the file as well as a person in the room. Foreign-language evidence, contracts, discovery documents, and exhibits for USCIS or court filings are handled by our translation team, with a signed Certificate of Translation Accuracy in the format US courts and USCIS expect. That work lives on our certified translation and document translation services pages. Foreign-language audio in the record, recorded calls, and deposition video can be transcribed verbatim through our audio transcription service, with certified English translation on request. One provider across the spoken and written sides keeps names, dates, and terminology consistent from the deposition room to the exhibit list.
Four steps from inquiry to invoice. Most bookings are confirmed the same day.
Tell us the language and dialect, the setting, the date and location, and any case-specific context you can share, through the quote form or at +1 (833) 282 8883. A conflict note on named parties helps us assign cleanly.
A project manager replies with a written quote, usually within 60 minutes during business hours, and confirms the interpreter's qualifications and any travel before you commit.
The interpreter is briefed on the setting, the parties, and any terminology or case files you provide, and arrives ahead of the start time on the day.
We confirm the time spent and bill to your matter or purchase order reference. For a case that runs to multiple dates, we hold the same interpreter where the schedule allows.
Almost everything that reaches us from a law firm is confidential, and much of it is privileged. Every interpreter signs a confidentiality and non-disclosure agreement before their first assignment, and we will sign your firm’s own NDA or protective-order acknowledgment instead if that is simpler for your risk team. Case details go to the interpreter assigned to your matter and no further.
Interpreters working legal matters are briefed on the ground rules that protect you: relay everything said, volunteer nothing, decline side conversations with the client, and flag on the record when something needs repeating. In an attorney-client meeting the interpreter is a conduit, and a disciplined one is part of what keeps the conversation privileged in practice, not just in principle.
We are based in Manhattan and place interpreters in every major US metro, including New York, Los Angeles, Chicago, Houston, Dallas, Miami, San Francisco, Washington DC, Boston, Atlanta, Seattle, and Phoenix. One call covers a deposition in Houston on Tuesday and a hearing in Chicago on Thursday; see our US locations for full coverage.
Demand follows the local caseload. A Spanish interpreter is the most requested legal assignment nationwide, and a Mandarin interpreter is a regular booking in commercial and immigration matters on both coasts. The full list of 326 languages includes the rare ones immigration dockets turn on.
As a guide, on-site interpreting in the US market typically runs $45 to $95 per hour, and certified court and deposition work sits toward the top of that range, sometimes above it in high-demand languages. A 2-hour minimum is standard practice. Trials, arbitrations, and long depositions are usually quoted as half-day or full-day rates instead, which works out better for you than an hourly meter running through recesses.
Four things move the number: the language, the required credential, the notice you give, and travel. Telephone interpreting is billed per minute and suits short client contact. In most cases none of this should surprise you on an invoice; minimums, travel, and cancellation terms are itemized on the written quote, and your quote confirms the exact price before you commit.
