Which deadlines still get the extra business day?

Deadlines that a statute, regulation or form instruction sets as a number of days. The Policy Manual's examples are the response period for a Notice of Intent to Deny (30 days at most) and the time to file Form I-290B after an I-485 denial (30 days if served in person, 33 days if served by mail). The same rule applies to mailed responses to a Request for Evidence (RFE).

Which deadlines no longer get it?

Deadlines that come from an eligibility rule instead of a count of days. USCIS's example is filing before a 21st birthday. The Policy Manual uses a special immigrant juvenile (SIJ) petition, which must be filed while the person is under 21. If the 21st birthday falls on a weekend or federal holiday, USCIS will not extend the deadline to the next business day.

Does a weekend count when USCIS counts days?

Yes. Saturdays, Sundays and federal holidays all count as days. Only the last day matters: if it lands on a Saturday, Sunday or federal holiday, the deadline moves to the end of the next day that is not.

Is the deadline based on when I mail it or when USCIS gets it?

When USCIS gets it. The regulation says USCIS records the receipt date as the actual date the request arrives at the filing location. A paper filing mailed before the deadline but received after it is late, unless the next-business-day rule applies.

Can you show a worked example?

The Policy Manual gives one. An I-485 denial is dated August 2, 2022 and served by mail, so the person has 33 days to file Form I-290B. Day 33 is Sunday, September 4, 2022. Monday, September 5 is Labor Day. So a paper I-290B received on Tuesday, September 6, 2022 is on time.

Does this affect online filings?

Online filings are received the moment you submit them, so they never get the extra business day. An online filing submitted on a Saturday counts as received that Saturday.

How long do I have to answer an RFE or NOID?

The notice states the deadline. An RFE can give at most 12 weeks (84 days) and a NOID at most 30 days. If USCIS mailed the notice, 3 days are added, so at most 87 days for an RFE and 33 days for a NOID. If the last day falls on a weekend or federal holiday, a mailed response received the next business day is on time.

I planned my filing using the 2023 rule. What now?

For paper filings received on or after October 23, 2026, the 2023 birthday rule no longer applies. USCIS says it delayed the effective date by one month to give notice to people relying on the old policy. If an age deadline is close, plan for the filing to arrive before the birthday.

USCIS Changes How It Counts Filing Deadlines That End on a Weekend (2026)

Executive summary

On September 23, 2026, USCIS issued Policy Alert PA-2026-15, "Definition of Day for Purposes of Filing Deadlines." It took effect on October 23, 2026 and applies to paper-based filings received on or after that date. On October 23, USCIS published a technical update that added the guidance to Volume 1 of the Policy Manual.

The basic rule comes from the regulation at 8 CFR 1.2. When a deadline is counted in days, every day counts, including Saturdays, Sundays and federal holidays. If the last day falls on a Saturday, Sunday or federal holiday, the deadline moves to the end of the next day that is not one of those days.

USCIS now applies that rule only when a statute, regulation or form instruction sets the deadline as a number of days. Examples in the Policy Manual include the 30-day maximum response time for a Notice of Intent to Deny (NOID) and the 30 days (33 if the denial was mailed) to file Form I-290B after an I-485 denial.

The change is for deadlines that are not counted in days. USCIS's example is a requirement to file before a person's 21st birthday. Since 2023, USCIS had treated such a filing as on time if it arrived on the next business day after a weekend or holiday birthday. From October 23, 2026, it does not.

Electronic filings are not affected. USCIS treats an online filing as received the moment it is submitted, so it never gets the extra business day, on any day of the week.

What changed, in plain English

USCIS does not accept paper filings on Saturdays, Sundays or federal holidays. So when a deadline counted in days ends on one of those days, USCIS gives you until the end of the next business day. That rule did not change. It still covers deadlines like RFE and NOID responses and appeals.

What changed is deadlines tied to a birthday or age. In 2023 USCIS started giving those the extra business day too. That stopped on October 23, 2026. If a person must file before turning 21, and the 21st birthday falls on a Saturday, USCIS will not wait until Monday. The filing must arrive while the person is still under 21.

Remember that USCIS counts the day it receives a paper filing, not the day you mail it. And an online filing counts the day you submit it, even on a weekend, so it gets no extra day.

USCIS says it is returning to how it read the rule before 2023, and it points to a 2025 Supreme Court decision about how the word "day" works in deadlines.

What the policy says

When a statute, regulation or form instruction sets a filing deadline in days, USCIS applies the regulatory definition of "day" in 8 CFR 1.2. Saturdays, Sundays and federal holidays count, but if the last day falls on one of them, a paper filing is on time if USCIS receives it by the end of the next business day.
USCIS does not apply the definition of "day" to deadlines that are not counted in days and instead come from a substantive eligibility requirement, such as filing before a person's 21st birthday. Those deadlines do not move to the next business day.
Electronically submitted requests are received immediately on submission, so USCIS does not extend the period for online filings.
The guidance is effective October 23, 2026 and applies to paper-based filings received on or after that date. It replaces the March 29, 2023 guidance (PA-2023-10) on this point and revises Volume 1, Part B, Chapter 6, Section E in its entirety.
USCIS cites Monsalvo Velasquez v. Bondi, 604 U.S. 712 (2025), and says the one-month delay before the effective date gives enough notice to people who planned filings under the 2023 policy.
