US STEM OPT 24-Month Extension for Pakistani Students (2026)

What is the STEM OPT extension, and who is it for?

Every F-1 student who finishes a US degree can apply for optional practical training, usually 12 months of work in their field. STEM graduates get more. A qualifying STEM graduate can add a 24-month extension on top of the standard 12 months of post-completion OPT, which USCIS confirms on its STEM OPT extension page.

The reason it exists is policy, not favour. The United States wants to keep science and engineering talent for longer, so it built a longer runway for those fields. For a Pakistani student the maths is simple. A one-year OPT is barely enough time to prove yourself and, in most years, take one shot at the H-1B lottery. Three years gives you two or three shots and a real career start. If you have already read our guide on how OPT work authorization works after a US degree, treat this as the sequel that runs after that first year.

Note what the extension is not. It is not a new visa. You stay in F-1 status the whole time, still tied to the school that issued your Form I-20. It is not automatic either. You apply, you pay, you wait for a new Employment Authorization Document, and you follow reporting rules that your first OPT year did not have.

Who is eligible for the 24-month extension?

Four things have to line up at the same time. Your degree has to be on the official STEM list. You have to be on a valid period of post-completion OPT right now. Your employer has to be enrolled in E-Verify. And you have to file before your current card expires.

The DHS eligibility guidance sets out the core tests, and it is worth reading in full on the Study in the States eligibility page. In short you must hold a bachelor's, master's or doctoral degree from an accredited, SEVP-certified school, the degree has to sit in a designated STEM field, and your current employment has to be tied to that field.

The prior-degree route many students miss

Here is a rule that catches people by surprise, in a good way. If your current job relates to a STEM degree you earned earlier, you may be able to use that earlier degree to qualify for the extension even if the degree you just finished is not STEM. A student who did a STEM bachelor's and then a non-STEM master's can sometimes still get a STEM extension based on the bachelor's, provided the earlier degree is from an accredited SEVP school and the work relates to it. It is narrow, and your DSO decides, but it is real, so raise it if it might apply to you.

Which degrees count as STEM, and how do you check?

Do not guess from the name of your programme. Whether a degree is STEM is decided by its CIP code, the six-digit classification your school reports to SEVIS, checked against the DHS STEM Designated Degree Program List. Computer science, most engineering fields, mathematics, actuarial science, many data and analytics programmes, and a growing set of business-analytics and management-science degrees are on it. Plenty of programmes that sound technical are not.

Ask your DSO for the exact CIP code printed on your I-20 and check it against the current list before you build any plans around the extension. If the code on your I-20 is wrong, that is a fixable problem, but only your school can correct it, and only before you file.

What must your employer provide?

The extension is built around a real training relationship, not just a job. That is why the employer rules are stricter than for your first OPT year.

The employer has to give you at least 20 hours of paid work a week and must be enrolled in E-Verify, a pair of conditions USCIS states plainly on its STEM OPT page. The role has to be paid at a rate comparable to what the employer pays its own similarly placed workers, and the training has to relate directly to your STEM degree. A volunteer position, an unpaid internship, or self-employment does not qualify.

• The employer must be enrolled in E-Verify and give you its E-Verify company identification number for the training plan.
• Paid work of at least 20 hours a week is required, and the pay must match what peers in the same role earn.
• Training must be run by the employer itself, which is why most staffing-agency and third-party placement arrangements do not fit.
• Your work has to relate to the STEM degree that qualifies you, not to some unrelated side skill.

Third-party placement is the sharpest edge here. If a firm hires you and then farms you out to a client site where the client, not your employer, controls your training, DHS has said that arrangement generally fails the rules. Before you accept an offer, be sure the company that signs your training plan is the company that actually trains and supervises you.

What is the Form I-983 training plan?

The Form I-983 is the heart of the STEM extension. It is a training plan you and your employer complete together before your DSO can recommend the extension. USCIS is clear that the plan has to identify the specific skills and knowledge you will gain, explain how the work delivers them, describe how your performance will be measured, and set out how you will be supervised.

It is not a one-and-done form. You and your employer revisit it. There is a self-evaluation at the twelve-month mark and a final evaluation at the end of the 24 months, both signed. If you change employers, you file a fresh I-983 for the new one. Treat the plan as a live document, because the school and DHS can ask to see it, and a plan that does not match the work you are actually doing is a problem.

How do you apply, step by step?

The sequence matters, because two clocks run at once. One is your current OPT expiry. The other is the 60-day limit that starts when your DSO makes the recommendation.

1. Confirm your degree is STEM and your employer is on E-Verify. Get the employer's E-Verify number.
2. Complete the Form I-983 with your employer and give it to your DSO.
3. Your DSO reviews the plan and enters the STEM OPT recommendation in SEVIS, then issues you a new I-20 showing it.
4. File Form I-765 with USCIS, online or by mail, requesting the extension. You may file Form I-765 up to 90 days before your current OPT card expires, and you have to file within 60 days of the day your DSO enters the STEM recommendation in SEVIS, the timing described in the DHS SEVIS Help Hub.
5. Pay the USCIS filing fee and, if asked, attend a biometrics appointment.
6. Wait for the decision. Keep working while it is pending if you filed on time, then start again on the new card once approved.

If your first OPT expires while the extension is still pending, and you filed on time, USCIS automatically extends your work authorization by 180 days while it decides, as set out in the DHS student eligibility guidance. That safety net only opens if you filed before the old card ran out, which is why the 90-day head start exists. File early. Do not wait for the last week.

What does it cost, and how long does it take?

The main cost is the USCIS filing fee for Form I-765. That fee has moved more than once under recent fee rules, and older pages still show outdated figures, so we are not going to print a number that could be wrong the day you read it. Check the current amount on the official USCIS OPT page and the I-765 fee schedule before you pay, and budget for the possibility that online and paper filing carry different fees. Some students also pay a lawyer or an advisor, which is optional.

Processing time is the other variable. It swings with USCIS workload and is not a fixed figure, so treat any timeline you hear as an estimate rather than a promise. The practical protection is the automatic extension of your work authorization while the case is pending, which is exactly why filing early matters more than guessing the queue. If a US student visa cost breakdown would help you plan the wider budget, our guide on F-1 visa costs and SEVIS from Pakistan sets out the earlier stages.

What are the reporting rules once it starts?

Your first OPT year had almost no ongoing duties. The extension has real ones, and missing them can end the extension even if everything else is perfect.

The DHS reporting guidance, laid out on the Study in the States reporting page, sets two rhythms. There is a validation report every six months, where you confirm with your DSO that your name, address, employer and employment status in SEVIS are all correct. And there is a change report: any change to that information, including losing your job, has to reach your DSO within 10 days.

Across the whole 24-month extension you are allowed a further 60 days of unemployment on top of the 90 from your first OPT year, so the running total is a maximum of 150 days of unemployment before your status is at risk, a limit USCIS spells out on its STEM OPT page. Count them carefully. If you are between jobs, the days add up fast, and once you cross 150 you are out of status. Keep a private tally and do not rely on anyone else to keep it for you.

Which mistakes cost students the extension?

Most refusals and status problems come from a short list of avoidable errors. Read this list twice.

• Filing late. The window closes when your current OPT card expires, and there is no reopening it.
• Working for an employer that is not on E-Verify, or one that farms you out to a client that controls the work.
• Letting unemployment days pile up past the 150-day ceiling while you look for the next role.
• Treating the I-983 as a formality, then doing work that does not match the plan you signed.
• Forgetting the six-month validation, or reporting a job change weeks after it happened rather than within 10 days.
• Assuming a technical-sounding degree is STEM without checking the CIP code on the I-20.

The through-line is that this is a monitored status, not a free pass. If you have already dealt with a delay such as 221(g) administrative processing at the visa stage, you know how much US immigration rewards clean, on-time paperwork. The extension is the same discipline, stretched over three years.

What does a realistic timeline look like?

Take a Pakistani student, call her Hania, who finishes an MS in Computer Science in May 2026 and starts her first OPT in July 2026. Her CIP code is on the STEM list, and she checked it in her final term.

By early 2027 she has a full-time job at a company on E-Verify. Her 12-month OPT ends in July 2027. She does not wait. In April 2027, about 90 days before expiry, she sits with her employer, completes the Form I-983, and hands it to her DSO. The DSO enters the recommendation and issues a new I-20 in mid-April. She files Form I-765 within days, well inside the 60-day limit, and pays the current USCIS fee.

Her old card expires in July 2027 while the case is still pending. Because she filed on time, her work authorization continues automatically for up to 180 days, so she keeps working without a gap. USCIS approves the extension over the summer, and her new EAD runs to July 2029. She files her twelve-month I-983 self-evaluation in July 2028, keeps her six-month validations current, and reports a mid-2028 job change to her DSO inside 10 days. Three years of US experience, no break, no status problem. That is what the rules look like when they are followed on time.
