The Portuguese we are asked to interpret is Brazilian far more often than European, and the difference is not academic. Our office is in New York and our Portuguese interpreters work nationwide, so for an in-person hearing or clinic visit we assign one based near you and for phone or video we can usually connect the same day. The first thing we settle at intake is where the speaker learned Portuguese, and whether they actually speak it or Cabo Verdean Creole.
By state, Portuguese ranks third in Massachusetts behind only English and Spanish, and about 139,000 Floridians speak it, the bulk of them Brazilian. New England is the other center of demand: the Massachusetts Trial Court lists Portuguese among its most requested languages, and lists Cabo Verdean Creole separately, because Creole is a different language and not a variety of Portuguese.
Brazilian or European? Ask first. They are one written language and two spoken ones. A Brazilian interpreter can follow a witness from the Azores only with effort, and a Lisbon-trained interpreter is a poor fit for a defendant from Minas Gerais. We match the interpreter to the speaker's side of the Atlantic, and we treat a Cabo Verdean client as a separate question, asking whether they want Portuguese or Creole before anyone is booked.
Portuguese has a national oral exam for court interpreters through the NCSC, and California is among the states that certify Portuguese court interpreters; others rely on registered or qualified ones. Give us the court and the case type and we match the credential it expects, along with the Brazilian or European Portuguese the case actually needs. We work for courts, attorneys and law firms directly; we are a private agency, not a court-appointed vendor.
Hospitals that take federal money must supply a Portuguese interpreter at no cost, and the failure we see again and again is a Brazilian patient handed a Spanish interpreter because the two languages sound close from the outside. They are not interchangeable in a medical history, and a misread symptom is a real risk. Video covers most consultations; we send someone in person for a difficult conversation, a mental health assessment, or an older patient who does poorly on a screen.
Brazilian family petitions and asylum cases are the bulk of this work. The interpreter renders exactly what is said and does not fill the gaps a nervous applicant leaves, because at an asylum interview the officer is weighing the applicant's own account, not a tidied one. We match the variety, brief the interpreter to add nothing, and we do not put a relative in the chair.
In a US filing the Portuguese paperwork is usually Brazilian, and each Brazilian civil record is issued by a Cartorio de Registro Civil in the state where the person was born, in a layout that changes from one state to the next. A certidao de nascimento carries a matricula number, the livro and folha references, the averbacoes in the margin that record a marriage, divorce or name change, and an embossed or stamped cartorio seal; a translator who treats those margin notes as clutter has just deleted a divorce. Many older certidoes are handwritten, and because a modern reprint can carry a different spelling, we translate both versions whenever both are supplied. For a document from Portugal you are looking at a certidao of the assento de nascimento from a Conservatoria do Registo Civil under the IRN, frequently the international multilingual form, and even that leaves Portuguese-only entries to be translated. Accents and name order are where the friction lands: a Joao whose passport has dropped the tilde, or a mother's surname that comes first in the Brazilian order and last on the US form. We match the passport, keep the original order with a note, and reproduce the issuing cartorio and state as printed. The full document service is at certified translation.

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