Prism Linguistics arranges Siswati interpreters for asylum interviews, court hearings and medical appointments across the United States, in person, by phone or by video, for speakers from Eswatini and South Africa, and provides certified English translation of the affidavits, letters and statements that support their filings.

siSwati and Swazi are two names for one language, so if you have been quoted for a Swazi interpreter and a Siswati interpreter separately, they are the same booking. It is the language of Eswatini and of about 2.8 percent of South Africans at the 2022 census, most of them in Mpumalanga on the Eswatini border. Our office is in New York and our Siswati interpreters work wherever the asylum office, the courtroom or the clinic sits, in person where a linguist is within reach and by phone or video where reaching one quickly matters more.
Siswati is an Nguni language close to Zulu, and a Zulu interpreter is what many agencies send when a Siswati one is requested. For a routine clinic visit that substitution often holds. At an asylum credibility interview or under cross-examination it does not, because a Siswati speaker from rural Eswatini may not keep pace with a Zulu interpreter, and the differences in vocabulary and pronunciation land on exactly the words an officer is weighing.
The paperwork is in English, so the person who needs the interpreter is usually not the applicant. Both Eswatini and South Africa school and register in English, and working-age speakers tend to manage. It is the parent, the older relative, and anyone recounting trauma under stress who needs Siswati, and we ask the country and district at intake before we assign.
The asylum interview is where a Siswati interpreter has to be exactly right. An officer reads the applicant's own words, the hesitations and the small contradictions, and a Zulu speaker approximating Siswati hands over an account that drifts from what was said. We assign a Siswati interpreter matched to the speaker's country and district and brief them to render each answer as spoken, adding nothing and softening nothing. A bilingual relative never sits in that chair. Where the story runs through places in Eswatini or Mpumalanga, we match the interpreter so a place name or a family reference is not lost on the way to the record.
Siswati reaches the courts through immigration hearings and through the family, civil and criminal matters where an Eswatini or South African party speaks it. No state runs a certification exam in Siswati, so a court works from a qualified interpreter, usually by phone or video, and we tell the bench and the attorneys what that interpreter's background is before things begin. We do not quietly send a Zulu interpreter on a Siswati booking. Prism takes this work from courts and law firms directly, and we are a private agency and not a vendor appointed by any court, which is the honest position and worth stating.
In a hospital an older Siswati-speaking patient is too easily left to a relative or a Zulu-speaking staff member, and a consent talk or a mental-health assessment is no place to approximate. Any provider that takes federal funding has to supply a Siswati interpreter at no cost to the patient, and most families never hear that this is a right. Video is enough for a consultation or a specialist review. For discharge planning, for psychiatric work, or for a frail patient who does better with a person present, we send an interpreter in person where one is close enough to attend.
Most Siswati filings need no certificate translated. Eswatini's Ministry of Home Affairs and South Africa's Department of Home Affairs both print birth, marriage and death certificates in English, so USCIS asks for no translation of them, and we say so rather than sell one. What needs a Siswati translator is the material around the record: an affidavit for a birth registered late, a letter from a chief or a church, a customary marriage statement, and the messages and voice notes filed as evidence. The trap here is the country name. Eswatini was Swaziland until 2018, and a Siswati document written before then names the old country; a translator who silently updates it to Eswatini creates a mismatch with the certificate it is meant to support. We render the name as written, add a translator's note where the history needs explaining, and deliver a signed Certificate of Translation Accuracy. The full document service is at certified translation.

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