New F-1 Fixed-Period Rule: Four Dates Families Must Track

Short answer: Beginning September 15, 2026, F-1 students admitted to the United States will no longer receive D/S on their I-94. They will receive a specific expiration date instead. Families will need to review four timelines together: passport, visa, Form I-20, and Form I-94.

Important legal boundary

The Department of Homeland Security (DHS) published the final rule on July 17, 2026. Its currently stated effective date is September 15, 2026. The rule is classified as a major rule subject to congressional review; if the effective date changes, DHS will publish a further Federal Register notice.

This article provides educational-planning information for families. It is not immigration legal advice. A student's individual status, extension, transfer, and travel plan should be confirmed with the school's designated school official (DSO), current USCIS guidance, and a licensed immigration attorney.

“Does this new rule affect my child?”

Several parents have asked us exactly that question.

The question followed the new DHS final rule. Two San Diego private schools also raised it in recent meetings with our team. Schools are paying attention, families are paying attention, and so are we.

The official rule is 156 pages long. This guide focuses on one practical question: what does it mean for a Chinese student who is studying, or preparing to study, in San Diego?

First, separate visa validity from immigration status

Many families assume that a child may remain in the United States as long as the visa in the passport has not expired.

That is not how the system works.

A visa is primarily used to apply for admission at the border. After a student enters the United States, immigration status and the I-94 admission record determine how long the student is authorized to remain.

Until now, most F-1 students have been admitted for D/S.

D/S means “duration of status.” Rather than listing a calendar expiration date, an F-1 student's I-94 generally shows D/S. As long as the student remains enrolled in a full course of study, keeps the I-20 and SEVIS record valid, and complies with all F-1 requirements, the authorized stay follows the program and any approved practical training. In many cases, a delayed graduation, school transfer, or move to a higher level of study could be handled through updates to the I-20 and SEVIS.

The central change in the new rule is the replacement of D/S for F, J, and most I nonimmigrants with a fixed admission period.

What replaces D/S: a date on the I-94

After the rule takes effect, an F-1 student admitted to the United States will receive a specific expiration date on the I-94 rather than D/S.

The F-1 admission period will generally reflect the time needed to complete the program shown on the I-20, up to a maximum of four years. A student may be admitted up to 30 days before the report date or program start date. The student also receives 30 days after the program end date or four-year maximum to depart or seek another lawful status arrangement. Neither 30-day period counts toward the four-year maximum.

For example, suppose a student begins grade 7 in August 2026 and the private middle school issues an I-20 ending in June 2028. The admission period will generally be tied to that June 2028 endpoint. It will not automatically extend through high-school graduation.

Families must therefore review four dates together:

Passport expiration
F-1 visa expiration
I-20 program end date
I-94 admit-until date

For determining how long the student is authorized to remain inside the United States, the I-94 is especially important.

What changes for San Diego private-school families

Many families we support send their children to San Diego private schools beginning in middle or high school. Three changes deserve particular attention.

Middle school to high school requires earlier status planning

In the past, many families focused on having the schools update the I-20 and SEVIS record. Under the new rule, families also need to confirm:

whether the new high school is SEVP-certified;
whether a SEVIS transfer is required;
whether the new I-20 end date extends beyond the current I-94 date; and
whether the student must apply to USCIS for an extension of stay.

We generally recommend reviewing the next school and the immigration timeline four to six months before middle-school graduation.

Transfers during the first academic year become more restricted

Under the new rule, an F-1 student below the graduate degree level generally may not transfer schools or change educational objectives during the first academic year of a program unless SEVP authorizes an exception for extenuating circumstances. Examples in the rule include school closure, a prolonged inability to hold in-person classes after a natural disaster, or a student's need to change schools to complete elementary or secondary education.

This matters in everyday family decisions. A student may discover after enrollment that the homestay is too far away, the school is not a good fit, or academic support is insufficient. A family should no longer assume that a first-year transfer will be available. The school's DSO must first help determine whether an exception applies.

The choice of school and homestay therefore deserves more work before enrollment: academic fit, transportation, ESL and learning support, and the school's international-student transfer process all matter. Careful selection is usually easier than trying to undo a poor fit later.

The post-completion period generally falls from 60 days to 30 days

Under the fixed-period system, an F-1 student generally has 30 days after completing the program and any approved practical training to depart, file for an extension, or seek another lawful status. If the student ends study or training early, the student must also depart or seek another lawful arrangement within 30 days of the actual end date.

For a middle- or high-school student, an early return home, terminated enrollment, sudden school change, or breakdown in a homestay or guardianship arrangement can move the timeline forward. Families should not rely only on the original I-20 end date after the DSO has updated SEVIS.

Who is less affected, and who needs more planning?

A short program that does not use F-1 status is not directly covered by this rule. A short F-1 program or a four-year bachelor's program that can be completed within one authorized admission period will also face less extension pressure in many cases.

Families should plan earlier when the student is:

moving from middle school through high school in the United States;
graduating late, taking a leave, or returning after a gap;
completing an undergraduate program that may take more than four years;
continuing directly from a bachelor's program to graduate school; or
pursuing a PhD, medical degree, STEM doctorate, or long research program.

These students are more likely to reach the I-94 date before completing the educational plan. They may need an extension of stay or a new admission after travel.

An I-20 update alone does not extend the authorized stay. Under the final rule, a student seeking an extension generally must submit Form I-539, an updated DSO-endorsed I-20, evidence of sufficient funds, status-compliance evidence, the required fee, and any biometrics USCIS requires. USCIS must receive a timely application before the authorized stay expires. If USCIS denies the request after the original admission period has expired, the student and dependents must depart immediately.

What about students already studying in San Diego?

If the student is currently in the United States with D/S on the I-94, there is no need to panic.

Under the transition rule, an F-1 student who is in the United States on September 15, 2026, is properly maintaining status, and was admitted for D/S may generally remain until the earlier of the program end date on the I-20 valid that day or four years after the rule's effective date. The student then retains a 60-day departure period.

This distinction matters: the new fixed-period system generally uses a 30-day departure period, but qualifying F-1 students covered by the D/S transition retain 60 days.

Travel is another important issue.

If a transition student leaves the United States after the rule takes effect and later applies to reenter in F-1 status, the student will generally receive a new fixed admission period. A winter trip home or summer vacation abroad can therefore move the student from the D/S transition into the fixed-period system.

Before international travel, the family should review the timeline with the school DSO and, when needed, an immigration attorney.

Our planning recommendations for San Diego families

The practical effect of the rule is that status management becomes a shared responsibility among the school, student, and family.

Download and verify the I-94 after every entry. Compare its admit-until date with the I-20 rather than checking only the visa.
Choose the school and homestay carefully. With tighter first-year transfer limits, the work before enrollment matters more.
Start four to six months early for a school transition or long program. Do not wait until the I-20 or I-94 is close to expiring.
Map middle school, high school, and college on one status timeline. Do not plan only for the current semester.
