Two counties, two sets of offices
Naperville is divided between DuPage County and Will County. County clerks hold the birth, death and marriage records for events that happened in their county, so the right office depends on where the event was registered, not on your current address.
The DuPage County Clerk issues certified vital records and marriage and civil union licenses, with office hours listed as Monday to Friday, 8:00 a.m. to 4:00 p.m. The Will County Clerk is at 302 N. Chicago St., Joliet, IL 60432, and charges $12 for one certified birth certificate copy and $4 for each extra copy of the same record ordered together.
The Will County Clerk states on its marriage license page that documents not in English must be accompanied by a certified English translation. The Illinois Department of Public Health’s Division of Vital Records in Springfield also issues certified birth records by mail, at $10 for a first standard copy, and notes that processing takes about 12 weeks.
What the Census says about language in Naperville
According to Census Bureau QuickFacts, 26.9% of people age 5 and older in Naperville speak a language other than English at home, and 22.5% of residents are foreign born (2020 to 2024). The 2025 population estimate is 153,114.
Our most requested languages are Spanish, Russian, Hindi, Urdu, Chinese, Vietnamese, Arabic and Czech, out of 100 offered. For any other language, ask before ordering.
North Central College and foreign transcripts
North Central College, at 30 North Brainard St. in Naperville, tells international undergraduate applicants with university coursework from outside the United States to supply course descriptions in English for each course. It also requires a course-by-course evaluation from an organization affiliated with or recognized by NACES, and names The Evaluation Company, World Education Services and Educational Credential Evaluators.
Credential evaluators publish their own translation rules. Check them first, then send us the transcript and any course descriptions that need to be put into English.
Courts for Naperville residents
The DuPage County portion of Naperville is served by the Eighteenth Judicial Circuit Court, 505 North County Farm Road, Wheaton, IL 60187. The Will County portion is served by the Twelfth Judicial Circuit, whose main courthouse is at 100 W. Jefferson St., Joliet, with a branch court at 375 West Briarcliff Road, Bolingbrook, that holds court proceedings only.
The Eighteenth Circuit says foreign language interpreters are provided at no cost to the person who needs one. It employs staff Spanish interpreters and uses telephonic and contract interpreters for other languages. A written interpreter request is filed with the Clerk and must be approved and signed by a judge. Its interpreter page covers spoken proceedings and does not describe a document translation service, so written exhibits in another language are yours to have translated.
Federal matters from both counties go to the Eastern Division of the Northern District of Illinois at 219 South Dearborn Street, Chicago.
Apostille route from Naperville
An apostille for an Illinois document is issued by the Illinois Secretary of State, Index Department. The department’s two offices are at 17 N. State St., Suite 1010, Chicago, IL 60602 and 111 E. Monroe, Springfield, IL 62756. There is no apostille counter in Naperville.
The state fee is listed as $2 per document, and requests use the Application for Authentication or Apostille, form I-213. If you mail the request, enclose a self-addressed, stamped envelope for the return. Confirm current walk-in and mail procedures on the Secretary of State’s site before you send originals.
If a translation must be notarized for Illinois, such as when it will receive an Illinois apostille, we hire a notary commissioned in Illinois to notarize the translator’s statement. We can also help you with the apostille request itself.
Translations for USCIS
Federal regulation 8 CFR 103.2(b)(3) requires that a foreign-language document filed with USCIS be accompanied by a full English translation, certified by the translator as complete and accurate, along with the translator’s certification of competence in both languages. That means summaries and partial extracts do not meet the rule. We translate the whole document, including stamps and handwritten notes, and attach the signed certificate. Acceptance is always decided by the agency.
