Immigration Nerds Tackles the September 15th Deadline: A Deep Dive into What Duration of Status Means for Every F-1 Student

For nearly 50 years, three words have governed how international students stay in the United States: duration of status. Under this framework, an F-1 student was admitted for as long as they were making progress in their program. A PhD candidate could take a sixth year to finish a dissertation. A surgical resident could move into a fellowship. A community college student could transfer to a four-year university. The person making those calls was the international student advisor, someone who knew the student, knew the program, and worked inside clear federal guidelines.

On September 15th, 2026, that ends. The Department of Homeland Security published a final rule on July 17th replacing duration of status with a fixed date stamped on the I-94, capped at a maximum of four years. Anything beyond that, a transfer, a change in field of study, practical training, the final credits of a degree will now require a formal application to USCIS, with a fee, and with no published standard for how those applications will be decided.

In this episode of the Immigration Nerds podcast, host Lauren Clark, Managing Attorney at Erickson Immigration Group, sits down with Dan Berger, Partner at Green and Spiegel and Academic Fellow at Cornell Law School, to break down exactly what this rule changes, who has to file, what date actually controls, and what it sets in motion for an agency already carrying more than 11 million pending cases. For anyone on LinkedIn who works in higher education, talent acquisition, global mobility, immigration law, or healthcare workforce planning, this episode is essential listening.

Duration of Status Was Working, And the Government Never Argued Otherwise

One of the most striking points Berger raises early in the episode is that the government never presented evidence that the duration of status framework was broken. Under the Administrative Procedure Act, agencies proposing new regulations are required to justify why a change is needed and to perform economic analysis. By Berger’s assessment, that simply was not done effectively.

The existing system delegated oversight to designated school officials (DSOs) who tracked student progress, extended I-20s when warranted, and operated within clear federal guidelines. This worked because academic timelines are inherently unpredictable. A PhD student’s experiments may run longer than expected. A student from a high school without a science lab may need an extra semester to complete a chemistry major. Under duration of status, those were academic decisions made by academic professionals. Under the new rule, they become immigration decisions made by USCIS officers.

“It may seem logical to have a fixed expiration date, but sometimes you just don’t know how long a program is going to take. The school is delegated to keep track of the individual and to follow along. With this new rule, that would be up to an immigration officer.” — Dan Berger, Partner at Green and Spiegel, Academic Fellow at Cornell Law School

The Practical Impact Is Staggering And Full of Unknowns

The episode methodically walks through the specific scenarios that will now require a formal USCIS application where none was previously needed. The scope is enormous:

• A PhD program that extends beyond four years will require an extension application filed with USCIS, subject to discretionary approval, with no published standard for decision-making.

• OPT (Optional Practical Training) after graduation will now require both an extension of student status and a work card application. Previously, students only needed to apply for the work card.

• STEM OPT the two-year extension for STEM graduates, may push students past their four-year cap before they even complete the full benefit.

• Changing education levels (e.g., bachelor’s to master’s to PhD) will require multiple extension applications at each transition.

• The rule prohibits completing two degrees at the same education level sequentially, meaning a student who wants a master’s in engineering followed by an MBA may no longer be able to do so on an F-1 visa.

• It remains unclear how dual degree programs (such as MD-PhD programs) fit into the new framework.

• Foreign journalists on I visas lose duration of status and receive a 240-day window, with no clear guidance on extensions raising concerns about press freedom.

And the critical unanswered questions keep stacking up: How early can extension applications be filed? What evidentiary standard will officers apply? What happens if processing takes months and a medical resident’s training is interrupted? None of this has been addressed in published guidance or FAQs.

“How early can this be filed? Can I file eight months early? Six months early? What standard will be used to decide? Is it just up to the immigration officer to say, "I don’t think you’re really ready to do a PhD"? We don’t have those answers.” — Dan Berger

USCIS Cannot Handle This Volume, And History Proves It

Berger provides critical historical context that makes the current rule even more concerning. The Immigration Service attempted something similar in 1973 and again in 1981. Both times, the agency backed off because the administrative burden was unmanageable. At that point, the international student population was a fraction of what it is today.

Today, more than one million international students and exchange visitors are in the United States. The rule is projected to add approximately 400,000 new applications per year to an agency that already carries over 11 million pending cases. And that agency, by multiple accounts, has lost roughly 20% of its staff over the past year through attrition and early retirement. Contracts with contractors running mail rooms have lapsed. Technology upgrades have stalled.

As Berger puts it plainly: fewer people, more cases, less training, more discretion. The result is a recipe for delay, inconsistency, and denials without adequate reasoning.

“You’ve got an agency that has fewer people that’s being required now to do more extreme vetting, so they’re spending more time on each case, and they have fewer people to do those cases. And by doing this, they’re gonna be adding hundreds of thousands of additional cases.” — Dan Berger

The Chilling Effect on America’s Talent Pipeline Is Already Underway

Berger is direct about the broader consequences: this rule will accelerate a chilling effect on international student enrollment that is already measurable. Applications to U.S. institutions from international students have been declining due to uncertainty around enforcement, profiling concerns, and questions about post-graduation work opportunities. This rule adds another layer of uncertainty on top of an already fragile pipeline.

The stakes are especially high in STEM fields, where a large percentage of graduate students are international. These are the researchers, engineers, and scientists who feed directly into the U.S. innovation economy. When they choose Canada, Australia, or Europe instead, the talent and the economic activity they generate go with them.

Berger shares a conversation with a doctor from Pakistan who spent years planning every detail of his path to a prestigious U.S. residency. The prospect that he might now be unable to complete his training, or do a fellowship afterward, or secure employment all because of discretionary decisions by undertrained officers makes the U.S. a harder commitment to justify.

“People don’t want uncertainty. If they’re told they may not be able to complete their training or may not be able to do a fellowship afterward, it may discourage people or may make people consider other countries. And that’s a hard gamble.” — Dan Berger

A Legal Challenge Is Coming, And It Has Strong Grounds

Berger expects a legal challenge to be filed within weeks. The most likely avenue is an Administrative Procedure Act (APA) challenge arguing that the government failed to follow proper procedure in issuing the rule. Specifically:

• The proposed rule received over 21,000 public comments an extraordinary volume, especially given that higher education institutions were simultaneously managing significant operational challenges.

• Many of those comments were highly detailed, including economic data, policy analysis, and expert testimony.

• Berger argues the government did not adequately respond to those comments or justify the rule with the required economic analysis.

• A fast-track judicial decision on whether to block the rule while litigation proceeds could come within 60 days.

Berger notes that while the government likely has the legal authority to make this change it is probably constitutional the procedural path to get there appears flawed. The failure to justify the rule and meaningfully engage with public comments creates a strong basis for an APA challenge.

News Nerd Update: What’s Happening Right Now in U.S. Immigration

Rob Taylor, Partner at Erickson Immigration Group, delivered key updates relevant to every employer and immigration professional:

TPS and EAD Court Rulings: Relief for Multiple Nationalities: Several recent court rulings have provided relief to TPS holders from Haiti, Somalia, and Ukraine regarding their TPS and employment authorization validity periods. The specifics are nuanced by nationality employers and individuals in TPS status should consult the full details at eiglaw.com.

$100K H-1B Fee Remains Blocked: The U.S. Court of Appeals for the First Circuit denied the government’s motion to stay a lower court ruling that vacated the $100,000 H-1B fee. As of now, the fee remains unapplicable. This is a positive development for employers filing H-1B petitions.

August Visa Bulletin: Limited Movement: The August Visa Bulletin showed minimal movement, with only a few months of advancement in select categories. This trend is expected to continue through October, when the new fiscal year brings additional visa numbers and potentially greater forward movement.

Quote Highlight

A standout moment from the episode:

“I think the idea of having immigration officers, probably without a lot of training, making these decisions relatively quickly in the number of minutes they have to review an application, and with a lot of discretion, is just, unfortunately, a recipe for delay. We may see cases denied just without a lot of good reasoning.” — Dan Berger, Partner at Green and Spiegel, Academic Fellow at Cornell Law School
