The way international students maintain lawful status in the U.S. is about to change.
On July 17, 2026, the Department of Homeland Security (DHS) published its Final Rule ending the long-standing Duration of Status (D/S) admission framework for F-1 students. Beginning approximately September 15, 2026, eligible F-1 students—including many on Curricular Practical Training (CPT), Optional Practical Training (OPT), and STEM OPT—will instead receive a fixed admission period and may need to file an Extension of Stay (EOS) with USCIS if they cannot complete their academic program before their authorized stay expires.
For thousands of international students, this raises an important question:
"Should you file a Change of Status with USCIS, or should you apply for an Extension of Stay?"
The answer depends on your current immigration status, graduation timeline, employment plans, and long-term goals. Making the wrong decision could affect your lawful presence, future immigration benefits, or even your ability to remain in the United States. That's why understanding your options now is more important than waiting until your admission period is about to expire.
In this guide, we'll explain what changed, who is affected, and how to determine which path may be appropriate based on your situation.
For nearly five decades, most F-1 students were admitted under Duration of Status (D/S). Instead of having a fixed expiration date, students could remain in the United States as long as they maintained valid F-1 status, complied with immigration regulations, and continued progressing in their academic program.
That system is ending.
According to DHS, these changes are intended to improve oversight of student immigration status by requiring periodic USCIS review rather than allowing students to remain under an open-ended Duration of Status framework.
Many Day 1 CPT students assume this rule only affects students graduating after September 15, 2026.
In reality, the Final Rule creates different outcomes depending on when you were admitted, whether you're already enrolled, whether you're using CPT or OPT, and whether your academic program extends beyond your authorized admission period.
Some students may not need to take immediate action because they qualify under transition provisions.
Others may eventually need to:
Understanding which category you fall into can help you avoid last-minute filing decisions.
These two USCIS processes are often confused, but they serve different purposes.
| Extension of Stay (EOS) | Change of Status (COS) |
|---|---|
| Keeps your current immigration classification. | Changes you into a different nonimmigrant classification. |
| Used when you need additional time under your existing status. | Used when moving from one visa category to another. |
| Example: F-1 student needs additional time to finish a doctorate. | Example: H-1B worker changes to F-1 student status. |
| Filed using Form I-539 (when applicable). | Often filed using Form I-539 or another applicable USCIS process depending on the status requested. |
A simple way to think about it:
Choosing the wrong option could result in unnecessary delays, additional expenses, or even a denial if you file under the wrong category.
Although not every international student will need to file immediately, now is the time to understand where you stand.
Generally, you begin discussing an Extension of Stay strategy with your DSO if:
Waiting until your authorized stay is about to expire could significantly reduce your options.
The good news is that many current students are protected by transition provisions under the Final Rule, but understanding those timelines early can help you avoid unnecessary stress later.
A Change of Status (COS) is generally considered when you are changing from one nonimmigrant visa classification to another, rather than remaining in your current status.
Examples may include:
Many professionals affected by layoffs or nearing the end of the H-1B grace period may consider a Change of Status to F-1 if they intend to continue their education while maintaining lawful presence in the United States.
However, a Change of Status is not automatically the right solution for every student. If you are already in valid F-1 status, your situation may instead require an Extension of Stay rather than changing to another visa category.
An Extension of Stay (EOS) allows eligible students to remain in the United States longer without changing their current immigration classification.
Under the Final Rule, this becomes significantly more important because students can no longer rely indefinitely on the Duration of Status framework.
Examples may include:
The Final Rule also confirms that students who timely file eligible EOS applications may continue pursuing their studies while USCIS adjudicates the request, subject to regulatory requirements.
Choosing between a USCIS Change of Status (COS) and an Extension of Stay (EOS) isn't simply about filing paperwork—it's about selecting the option that matches your current immigration status and long-term plans.
An Extension of Stay is generally appropriate when you want to remain in your current nonimmigrant classification but need additional time to complete your academic program.
A Change of Status, on the other hand, is designed for individuals who are moving into a different nonimmigrant status, such as changing from H-1B to F-1 after a layoff or beginning a new degree program.
The table below provides a general comparison.
| Your Situation | Recommended Option* |
|---|---|
| You're already in F-1 status and need more time to finish your degree. | Extension of Stay (EOS) |
| You're on Day 1 CPT and your program extends beyond your authorized admission period. | Extension of Stay (if eligible) |
| You're in the H-1B grace period and plan to return to school full-time. | Change of Status to F-1 |
| Your OPT or STEM OPT is ending, and you plan to begin a new academic program. | May involve a new F-1 admission or Change of Status, depending on your circumstances. |
| You're changing from another eligible nonimmigrant visa category into F-1. | Change of Status |
One question many international students ask is whether they should transfer schools, file an Extension of Stay, or take another action before the Final Rule takes effect.
The answer depends on your individual timeline.
The DHS Final Rule does not eliminate Curricular Practical Training (CPT), and DHS specifically declined to make changes to CPT—including Day 1 CPT—because it was outside the scope of this rulemaking.
However, the rule does change how students should plan their academic program.
If you're currently enrolled in a Day 1 CPT program, consider reviewing:
Planning early gives you more flexibility than waiting until your current authorization is close to expiring.
Another group significantly affected by this decision includes professionals who have recently lost H-1B employment.
Under current USCIS regulations, many H-1B workers receive a grace period of up to 60 consecutive days, or until the end of their authorized validity period (whichever is shorter), to take action after employment ends.
During that time, individuals commonly explore options such as:
For professionals who plan to return to school, a Change of Status to F-1 may provide a long-term academic pathway, whereas an Extension of Stay generally applies only when remaining in the same immigration classification.
Many students are also wondering whether they should extend their stay after OPT.
The Final Rule includes important transition provisions for students applying for post-completion OPT or STEM OPT.
Students who timely file for post-completion OPT or a STEM OPT Extension during the transition period generally do not need to file a separate Form I-539 Extension of Stay if they qualify for the temporary filing relief established by DHS. This transition relief applies only during the period described in the Final Rule unless DHS extends it through a future Federal Register notice.
If your OPT or STEM OPT is ending and you plan to begin another academic program, your next steps will depend on factors such as:
Students should review these details with their DSO before deciding whether a Change of Status or another immigration pathway is appropriate.
Many immigration problems can be avoided by planning ahead.
Here are several common mistakes students should avoid under the new rule.
The Final Rule shifts more responsibility to students to monitor their admission period and plan ahead.
Waiting until your authorization is about to expire may leave little time to gather documentation or respond to USCIS requests.
Not every student will need to file Form I-539 immediately.
Current students admitted under Duration of Status may qualify for transition provisions that preserve their current program end date, subject to the limits described in the Final Rule.
A Change of Status and an Extension of Stay are different immigration processes.
Submitting the wrong application can delay your case or require additional filings.
Understanding your immigration objective before filing is one of the most important parts of maintaining lawful status.
The Final Rule places greater importance on understanding when your academic program is expected to end.
If your degree may extend beyond your authorized admission period, discuss your options with your DSO well in advance.
Before deciding whether to pursue a Change of Status or an Extension of Stay, ask yourself:
Answering these questions now can help you make a more informed decision and avoid unnecessary immigration complications.
It depends on your situation. If you're already in valid F-1 status and simply need more time to complete your academic program, an Extension of Stay (EOS) may be appropriate.
If you're changing from another nonimmigrant status—such as H-1B—to F-1, you'll generally need to pursue a Change of Status (COS) instead.
The Final Rule does not eliminate Day 1 CPT. DHS specifically stated that changes to Curricular Practical Training (CPT), including Day 1 CPT, were outside the scope of this rulemaking.
However, students should review how the new fixed admission period may affect their long-term academic timeline and whether they may eventually need an Extension of Stay.
Possibly. Students who timely file for post-completion OPT or a STEM OPT Extension during the transition period may qualify for temporary filing relief described in the Final Rule.
However, students who need additional time beyond their authorized admission period after completing OPT should discuss their individual options with their DSO or an immigration attorney.
Eligible H-1B workers generally have up to 60 consecutive days, or until the end of their authorized validity period (whichever is shorter), to take action after employment ends.
During this period, individuals may seek new employment, pursue another eligible immigration option, or prepare to depart the United States.
The best time to begin planning is before your authorized admission period is close to expiring. Waiting until the last minute may reduce your options, especially if you need additional documentation, school approvals, or USCIS processing time.
The new DHS Duration of Status Final Rule changes more than just how long F-1 students may remain in the United States—it changes how international students should plan their academic journey and immigration strategy.
For CPT students, there is no one-size-fits-all solution. Some students may benefit from an Extension of Stay, while others may need to pursue a Change of Status depending on their current immigration classification, graduation timeline, and future plans. Understanding the difference between these options—and planning before your authorized stay expires—can help you avoid unnecessary stress and maintain lawful status.
If you're unsure which path is right for you, now is the time to review your timeline with your Designated School Official (DSO) and seek professional guidance before making any immigration decisions.
