USCIS: Age-based deadlines will no longer roll over past weekends

Starting October 23, 2026, USCIS will stop extending deadlines tied to a birthday, such as filing before turning 21, to the next business day when they fall on a weekend or federal holiday.

U.S. Citizenship and Immigration Services (USCIS) is changing how it counts certain filing deadlines, a shift that could cost some families a benefit if they wait until the last day. Under a policy alert published on September 23 (PA-2026-15), deadlines set by a substantive eligibility requirement, such as filing while under 21 or before a birthday, will no longer be extended when they fall on a Saturday, Sunday or federal holiday.

The change takes effect on October 23, 2026, and applies to paper filings received on or after that date. Until then, the 2023 guidance remains in place, under which a filing was accepted as timely if it arrived by the end of the next business day.

Deadlines counted in days, such as "within 30 days," are not affected. When the last day of such a period falls on a weekend or federal holiday, a paper filing received by the end of the next business day is still considered timely. Online filings are treated as received at the moment they are submitted.

USCIS said it is returning to its longstanding reading of the regulatory definition of "day," citing the Supreme Court's 2025 decision in Monsalvo Velasquez v. Bondi. The agency acknowledged that the switch may affect people who had planned filings around the 2023 policy, which is why it gave a one-month notice.

The rule matters most for families filing for a child who is close to turning 21. If the 21st birthday falls on a Sunday, waiting until Monday could mean losing eligibility. Immigration lawyers advise filing at least one business day before an age-based deadline and checking whether a deadline is counted in days or tied to an event.
