The language pair America runs on
More than 43 million people in the United States speak Spanish at home, and behind nearly every green card petition, naturalization file, school enrollment or court case built on their paperwork sits the same requirement: a certified Spanish to English translation that USCIS and every other authority will accept on the first submission. That is the order we fill more often than any other, from every state in the country — a complete, word-for-word rendering by a sworn human translator, issued on official company letterhead with a signed certificate of translation accuracy and our wet stamp, covered by a 100% acceptance guarantee. Express 24-hour turnaround is available coast to coast.
Behind the single word “Spanish” stand twenty-one national bureaucracies. Mexico issues an acta, Peru a partida, Spain a certificado literal — each with its own layout, seals, marginal annotations and abbreviations. The 500+ linguists in our network deal with these civil-registry formats every working day, and a second native speaker proofreads each document before it is certified. Since our first translation in 1991 we have aimed to be the most accurate and the most affordable at once — and if Spanish is the language you think in, you can read, ask and order entirely in Spanish.
