If you are mailing an application, petition, or appeal to U.S. Citizenship and Immigration Services (USCIS), a small rule change could decide whether it counts as on time. Starting Friday, October 23, 2026, USCIS will go back to an older, stricter way of handling deadlines that land on a Saturday, Sunday, or federal holiday. The biggest effect is on young people who must file before their 21st birthday.
What USCIS announced
On September 23, 2026, USCIS issued a policy alert (PA-2026-15) called "Definition of Day for Purposes of Filing Deadlines." It replaces guidance from March 2023. It applies to paper filings received on or after October 23, 2026.
USCIS does not accept paper filings on weekends or federal holidays. Under the 2023 guidance, if the last day to file landed on one of those days, USCIS generally treated a paper filing as on time if it arrived by the next business day. That included deadlines tied to an event, like a birthday. The new guidance keeps the extra day for some deadlines, but not all of them.
Deadlines written as a number of days: you still get the next business day
When a law, regulation, or form instruction gives you a set number of days, the old rule still works. If the last day falls on a Saturday, Sunday, or federal holiday, a paper filing is on time if USCIS receives it by the end of the next business day.
USCIS gives these examples:
- A Notice of Intent to Deny (NOID). The regulations say the response time will not be more than 30 days.
- An appeal or motion (Form I-290B) after a green card denial. You have 30 days if the denial was handed to you in person, or 33 days if it was mailed.
In USCIS's own example, the 33rd day was a Sunday and the next day was Labor Day, so a paper Form I-290B that arrived on Tuesday still counted as on time.
Birthday deadlines: no extra day anymore
Some benefits depend on your age when you file, not on a count of days. USCIS's main example is Special Immigrant Juvenile (SIJ) status, which children and young people who need protection, including some who came to the U.S. alone, apply for with Form I-360. The petition must be filed while the person is under 21.
Under the new guidance, if a 21st birthday falls on a weekend or holiday, USCIS will not move the deadline to the next business day. In practice, USCIS needs to receive the petition before the birthday, which may mean the last business day before it.
USCIS says it waited one month to start the change because some people had already planned their filings around the 2023 rule.
Filing online: no extra day either way
USCIS counts an online filing as received the moment you submit it. Online filings are not affected by weekend and holiday closures, so there is no next-business-day extension for them. If your deadline is Sunday, submit online by Sunday.
Key dates coming up
These federal holidays, from the U.S. Office of Personnel Management list, are days when USCIS does not accept paper filings:
- Wednesday, November 11, 2026 (Veterans Day)
- Thursday, November 26, 2026 (Thanksgiving)
- Friday, December 25, 2026 (Christmas)
What you can do now
- Find out how your deadline is written. Look at the notice, form instructions, or ask your lawyer. Is it "within 30 days," or "before you turn 21," or something else?
- Only count on the extra day for deadlines written in days. If your deadline is written another way, such as before a birthday, within a number of years, or before your status ends, plan for USCIS to receive your filing before any weekend or holiday.
- Remember that "received" is what counts, not the day you mail it. USCIS uses the date the filing actually arrives at the right address. Check the "Where to File" information for your form on uscis.gov and allow time for delivery.
- Turning 21 soon? If you or a child in your care may qualify for SIJ status, talk to a lawyer now. SIJ cases also need an order from a state court first, which takes time.
- Keep proof. Use tracked delivery and keep copies of everything you send, plus your receipt notice.
- This is a USCIS rule. It does not cover deadlines in immigration court. If you have a court case, ask your lawyer about those deadlines.
- Get free help. Call the National Immigrant Justice Center (NIJC) at 312-660-1370 (line open Tuesday–Thursday, 8:30 a.m.–4:30 p.m. Central Time) or the ICIRR (Illinois Coalition for Immigrant and Refugee Rights) Family Support Hotline at 855-435-7693.
