Certified Translation Chicago, USCIS Accepted | Protranslate

More than a fifth of Cook County was born abroad, and roughly a third of households speak a language other than English at home. That means a steady stream of birth certificates, diplomas and police records arriving from somewhere else and needing to be readable by an American agency. Here's what those agencies require, what a certified translation costs, and how to get the underlying Illinois record if you don't have it yet.

What Chicago and Illinois offices check

Illinois keeps no register of sworn translators, and neither does any other American state. Nobody is licensed to stamp a translation the way a court-appointed translator is in Poland, Mexico or Ukraine. What agencies want is a signed certification attached to the translation, and its wording matters more than any credential.

USCIS sets the federal standard at 8 CFR 103.2(b)(3): a full English translation of any foreign-language document, plus the translator's signed statement that the translation is complete and accurate and that they are competent to translate from that language. That standard applies identically at the Chicago Field Office and everywhere else, which is why a certification that works for a filing in Chicago works for one in Boston.

Every certified translation we deliver arrives as a PDF carrying that signed certification on Protranslate letterhead, formatted to match the original page for page. ✓ Accepted by USCIS, Illinois state agencies, courts and universities.

Getting the Illinois record before you translate it

Plenty of people ask us to translate a document they don't yet hold in certified form, which is wasted money. Illinois birth records come from the IDPH Division of Vital Records, and the numbers are worth knowing before you start: a certified copy of a birth record costs $15 for the first copy and $2 for each additional copy ordered at the same time. The catch is timing — processing runs to roughly twelve weeks from the date paperwork is received, which is far longer than most people expect and long enough to miss an immigration deadline.

One practical note for 2026: the Division's Springfield office at 925 East Ridgley Avenue closes permanently on 9 September 2026, with the new office opening at 110 W Lawrence Avenue on 14 September. If you're posting an application around those dates, check the address before you send it.

If the receiving country asks for an apostille, that comes from the Illinois Secretary of State, not from us and not from the health department. Order the certified copy, get it apostilled if required, then have everything translated in one go.

Documents Chicago clients send us most

What it costs

The price is on this page because hunting for it is the most annoying part of buying a translation. We charge per word rather than per page, which matters more than it sounds: most competitors cap a page at 250 words, so a 380-word Polish birth certificate gets billed as two pages, which at a typical page rate lands near $49. Here the same document is priced as 380 words, closer to $37.

The signed certification costs nothing extra, and neither does a revision. If an Illinois office ever rejects one of our certified translations on the grounds of the translation itself, we redo it free. Certified orders over $250 pick up an automatic volume discount, which matters for the multi-document files immigration attorneys send.

Certified or professional — which do you need?

Order certified when the document goes to an institution that will check it: USCIS, a court, a university admissions or credential-evaluation office, a state licensing board, a consulate. Anything with an official seal, and anything that proves who you are.

Professional translation is right when a human simply needs to read the text — contracts under negotiation, medical notes for a second opinion, employee handbooks, correspondence. Same translators, same review, minus the signed certification page, which is why it costs less. If the instruction sheet says certified, sworn or official, order certified.

The languages Chicago actually needs

About 21% of Cook County residents were born outside the United States, and roughly 35% of households speak a language other than English at home. The city's own language access programme names its five most-used languages as Spanish, Polish, Chinese, Hindi and Arabic — a list that looks like nowhere else in America, because of the Polish half of it.

That's exactly what arrives in our queue. Spanish to English certified translation leads by volume, mostly Mexican civil documents. Polish is the distinctive Chicago case: birth certificates, marriage records and university diplomas from Poland, in volume no other American city produces. After those come Mandarin and Cantonese, Hindi, Urdu, Arabic, Ukrainian, Russian, Korean and Tagalog. We work in more than 120 languages, so a Polish sworn-translator document or an Assyrian church record is routine rather than exotic.

Chicagoland and the rest of Illinois

Because none of this needs a counter visit, where you are changes nothing about the service or the price. We handle documents from Evanston, Skokie, Oak Park and Cicero, from Naperville, Aurora, Schaumburg and Joliet, and from Rockford, Peoria, Champaign and Springfield further out. The rules travel with you: the Division of Vital Records and the Secretary of State are state agencies, so what's accepted in the Loop is accepted downstate.

The document mix shifts by neighbourhood in a way locals will recognise. The Northwest Side and the northwest suburbs send Polish paperwork in volume, Pilsen and Little Village are heavily Mexican, Devon Avenue brings Hindi, Urdu, Gujarati and Assyrian, Albany Park is one of the most linguistically mixed square miles in the country, and Ukrainian Village does what its name suggests. Our overview of certified translation services in the USA covers the federal rules that apply wherever you file.

How long it takes

Standard turnaround on a short certified document is one to two business days. Express brings that down to 12 to 24 hours on most language pairs, and you see the express price before you commit, not after. Because our translators work across several time zones, a document uploaded on Friday evening in Chicago is often being worked on overnight rather than sitting until Monday. You get the PDF by email, and if an office wants ink on paper we courier a signed hard copy.

For Chicago law firms, hospitals and universities

A good share of our Illinois volume comes from immigration attorneys in the Loop sending client files in batches, hospitals translating patient records, and university offices handling foreign transcripts from applicants. The paperwork is repetitive in a useful way: the same document types, the same languages, the same deadlines every intake season.

For those accounts we set up monthly invoicing instead of card payment per job, keep the same translators on your files so terminology stays consistent, and sign confidentiality agreements where the work needs it. We're certified to ISO 17100, the international standard for translation services, and a member of the American Translators Association and GALA. For legal translation, every document goes through a second linguist before it's certified — the step most low-cost providers skip.

How ordering works

Upload the document, or a clear phone photo of it. Pick the target language and tell us if it needs to be certified. The price and delivery date appear straight away, so there's no waiting on a quote. Pay by card, and the finished translation lands in your inbox with the certification attached. No trip to an office in the Loop, no phone tag.

Protranslate has handled documents for more than 85,000 customers across 163 countries and holds a 4.8 out of 5 rating from 4,101 verified reviews, which makes it one of the top certified translation providers serving the US market. If you're not sure which service your document needs, ask before you order.
