CPT, OPT, and STEM OPT Under the New DHS Rule: What Changes on September 15

By The Immigration Compass | Published 2026-07-17

DHS published its final rule ending duration of status on July 17, 2026, effective September 15. Most coverage has focused on the four-year cap and left the question students actually ask unanswered: what happens to work authorization? The short answer is that eligibility for CPT, OPT and STEM OPT is largely untouched. What changes is the container they sit inside. This post works through all three, including the March 18, 2027 filing deadline and what DHS actually said about Day 1 CPT.

The Department of Homeland Security published its final rule ending duration of status on July 17, 2026 at 91 FR 44976. It takes effect September 15, 2026. Since the announcement, most coverage has focused on the four-year admission cap, and the question students keep asking has gone largely unanswered: what happens to work authorization?

The short version is that the rule changes almost nothing about eligibility for CPT, OPT, or the STEM OPT extension. What it changes is the container they sit inside. Your stay now has a fixed end date, and each form of practical training interacts with that date differently. This post works through all three, with everything sourced to the rule itself.

Key takeaways

• CPT: unchanged. Your DSO still authorizes it in SEVIS with an endorsed I-20, and no USCIS filing is involved. It just has to fit inside your admission period.
• Post-completion OPT and STEM OPT: eligibility unchanged, but after the transition window you must file an extension of stay alongside your work permit application.
• Mark March 18, 2027. File Form I-765 for post-completion OPT or STEM OPT on or before that date and you skip the extension of stay entirely.
• Day 1 CPT is not eliminated. DHS says so directly in the preamble, and separately declined requests to restrict CPT.
• Cap-gap survives for F-1 students with timely filed H-1B cap-subject petitions.
• Your DSO and official USCIS guidance are the authorities on your own record. No article can replace them.

Start here: how your admission period is calculated

Everything below depends on this, so it is worth getting right first.

Under the rule, your I-94 carries an Admit Until Date instead of "D/S". That date is the program end date on your Form I-20, capped at four years, plus 30 days to depart.

DHS clarified two mechanics in response to comments, and both are more favourable than people assume. The four-year maximum runs from your program start date, meaning the first day of classes or research, not the day you land. And F and J nonimmigrants may still arrive up to 30 days early, with DHS confirming those days are not counted against the maximum period of stay.

DHS worked an example itself. A commenter asked about a student holding a three-year I-20. DHS answered that the admission period on the I-94 will be three years plus the 30-day departure period, and the student must file for an extension of stay before the I-94 expires. An extension, when granted, runs to the new program end date or OPT end date on the I-20, again to a four-year maximum.

CPT under the new rule

This is the part most coverage is getting wrong by omission. CPT does not involve USCIS at all, and the rule does not change that.

DHS is explicit: the provisions in this rule do not affect the DSO's role in authorizing CPT, and only affect a student's employment eligibility status during the extension of stay process. Your DSO continues to update your SEVIS record to show CPT authorization and give you an endorsed Form I-20 before employment begins, exactly as the existing regulations require. There is no Form I-765 for CPT and no Form I-539 for CPT.

The single change is one of fit. CPT is part of your academic program, so it must be completed within your authorized period of admission. If your fixed period is about to expire, DHS states you will need to file a timely extension of stay with USCIS, not because of the CPT itself, but because your stay is running out.

Useful if you work on CPT DHS addressed the Form I-9 problem directly. Where an extension of stay is pending, your authorized employment period combined with the USCIS receipt notice is treated as unexpired for up to 240 days, or until USCIS decides, or until the CPT end date your DSO authorized on the Form I-20, whichever comes first. That gives your employer something concrete to verify against while you wait.

Does the rule eliminate Day 1 CPT?

No, and DHS answered this in writing rather than leaving it to interpretation.

A note on the term first. The regulation at 8 CFR 214.2(f)(10)(i) authorizes "a curricular practical training program that is an integral part of an established curriculum." Integral CPT is simply CPT in the regulation's own words. The phrase used in marketing, "Day 1 CPT," does not appear as a formal regulatory term. What it refers to is the same provision's exception to the one academic year requirement, available to students "enrolled in graduate studies that require immediate participation in curricular practical training." ICE puts it plainly: at the graduate level, your DSO may authorize CPT during your first semester if your program requires it.

Commenters argued the rule would eliminate Day 1 CPT, noting that fields such as business, computer science, and health sciences often build early practical training into the program. DHS responded that those comments misinterpret the rule, and stated that the rule does not prohibit or eliminate Day 1 CPT and makes no substantive changes to CPT.

Commenters on the other side asked DHS to restrict CPT, whether by carving out exceptions for certain fields or eliminating Day 1 CPT outright. DHS declined, stating it is not adopting changes to CPT at this time and that such amendments are beyond the scope of this rule.

DHS took pressure from both directions and moved in neither.

Post-completion OPT and STEM OPT: the March 2027 deadline

OPT is where the paperwork actually changes. Standard 12-month OPT and the 24-month STEM OPT extension both survive untouched as benefits. What changes is what you have to file.

The general rule after the transition: a student recommended for post-completion OPT must file both an extension of stay (Form I-539, or successor form) and a work permit application (Form I-765), and may not begin post-completion OPT unless the employment authorization is granted. DHS notes these are separate forms that can be filed at the same time, recommends concurrent filing, and says related cases will be adjudicated together. The extension of stay is only valid until the end date of the employment authorization.

The window that matters If you are in F-1 status under duration of status on September 15, 2026 and you timely file Form I-765 for post-completion OPT or a STEM OPT extension on or before March 18, 2027, you are not required to file an extension of stay at all. The I-765 is the only form you need. That date is 244 days after publication, and DHS reserves discretion to extend it in six-month increments by publishing a notice in the Federal Register.

Note row five. Leaving the country before filing costs you the reprieve even if you were otherwise entitled to it. If you are planning to file for post-completion OPT and also planning a trip home, the order matters.

For H-1B applicants DHS confirms the rule does not modify or remove cap-gap. F-1 students who are beneficiaries of timely filed H-1B cap-subject petitions continue to receive automatic extension of their authorized stay and employment authorization through April 1 of the relevant fiscal year, or until the H-1B petition's validity start date, whichever comes first.

The level restriction is prospective, and almost everyone is getting this wrong

This provision is driving most of the panic, and the panic is misplaced.

The rule prohibits a student who has completed a program at one educational level as an F-1 nonimmigrant from starting another program at the same or a lower level. Read alone, that sounds like it closes the door on a second master's.

But DHS states in the final rule that these provisions will be applied prospectively, and that any programs completed prior to the effective date of the rule will not be counted towards the limits. DHS says it clarified this specifically in the final rule, at 8 CFR 214.2(f)(5)(ii)(C).

In plain terms: the clock starts September 15, 2026. A master's finished in 2024 does not count. A master's finished next month does not count. The restriction only begins counting programs completed after the rule takes effect.

Two details worth holding. The restriction does reach change of status: DHS states someone who has completed a program as an F-1 nonimmigrant at one level cannot maintain F-1 status, depart and be readmitted in F-1 status, or otherwise obtain F-1 status, including through a change of status, for a program at the same or lower level. Note the trigger is completing a program as an F-1 nonimmigrant. A degree completed abroad, or while in another status, is a different question and one for a DSO or an immigration attorney rather than an assumption. And DHS gave itself authority to delay implementation of the prohibitions on changing schools, educational objectives, and levels, limited to two years from the effective date.

The caution DHS attached

DHS did not stop at "CPT is unchanged," and the rest matters more than the headline.

DHS states that the primary purpose of F-1 status is for foreign students to study in the United States and that it is not a pathway for employment. Because F-1 applicants must demonstrate the financial ability to support themselves, DHS says students should not be relying on future or prospective income from Day 1 CPT as their primary means to financially support themselves in the United States.

Read this twice If anyone has told you a CPT job will pay for your degree, they have described F-1 status backwards, and DHS has now said so in a live federal rule. Practical training is training that forms part of an established curriculum. It is not a funding plan and it is not an immigration pathway. You still have to show independent financial capacity to get the visa at all.

It is also worth knowing the company the term keeps in this document. In summarizing comments supporting the rule, DHS listed concerns about "Day-1 CPT" alongside pay-to-stay fraud, visa mills, and criminal enterprises. DHS did not adopt that characterization as its own finding, and its substantive response was the one quoted above. But the term now sits in the federal record next to fraud language, which is reason enough to be precise about what these programs are.

What this does not mean

• It does not mean any program is risk free. DHS declined to change CPT in this rule. It did not endorse any program, school, or provider. Training that is not genuinely integral to an established curriculum has the same problem today it had last week.
• It does not mean the date is settled. The rule is a major rule subject to congressional review, and DHS states that if the effective date changes at the conclusion of that review, it will publish a document establishing the actual effective date or terminating the rule.
• It does not replace your DSO. No article can tell you your program end date, your admission period, or whether a specific program fits your situation.

What to do with this

• Find your program end date and program start date on your Form I-20. Those two dates, not a four-year assumption, determine your admission period.
• If post-completion OPT or STEM OPT is on your horizon, work out whether you can file by March 18, 2027. Filing inside that window removes an entire application from your life.
• If you are filing for OPT, do not leave the country first. Departing before you file costs you the reprieve.
• Budget as though practical training income does not exist. DHS has now stated in writing that students should not rely on prospective CPT income as their primary means of support.
• Talk to your DSO before any transfer or change of level, particularly at the graduate level, where the new restrictions are strictest.
