STEM Optional Practical Training (OPT) is, at most, a 2-year period of temporary training and work authorization that is directly related to an F-1 student’s program of study.

F-1 students who completed a program of study in an approved STEM (Science, Technology, Engineering, and Math) field are eligible to apply for a 24-month extension of their Post-Completion OPT, which is called the STEM OPT extension, or STEM OPT.


Carefully read all instructions and information below before completing these forms:

Form I-983 Training Plan (See Step 1)

First, you will need to complete the Form I-983 Training Plan in order to submit your STEM OPT eForm request below.

STEM OPT I-20 eForm Request (See Step 2)

Next, you must request an updated I-20, which is needed to apply for the STEM Extension I-765. If your eID is active, log in using the button. If it has been 12+ months since you graduated, see alumni log-in below.

STEM Extension I-765 USCIS Application (See Step 3)

Finally, once you have your updated STEM OPT I-20, you are responsible for submitting your I-765 application to USCIS.

I-983 Training Plan

The Form I-983 Training Plan must be provided to ISSS in your STEM OPT I-20 Request eForm.

The I-983 does not need to be submitted to USCIS with the I-765, so don’t be surprised that there’s no convenient upload location for it in the online I-765 for STEM OPT.

Page 1 (Sections 1 and 2 of the I-983)

Page 1 must be completed by the student. Below are some common inquiry points:

  1. Your SEVIS ID starts with ‘N00’ and is at the top of your I-20s.
  2. CSU’s SEVIS school code is DEN214F00179000.
  3. You can leave the “Designated School Official (DSO) Name and Contact Information” field blank. The advisor who receives your application will fill in their own information.
  4. STEM OPT Requested Period will begin the day after your OPT expires and end 2 years after the expiry. For example, Mary’s OPT ends Dec 31, 2025. Her STEM OPT will begin Jan 1, 2026 and end Dec 31, 2028.
  5. Your “Classification of Instructional Programs (CIP) Code” is the number listed underneath your I-20 major in the middle of pg 1 on your I-20. It is written in the format XX.XXX. So the I-20 major “Dairy Science” has the CIP Code “01.0905,” so Mary would write “Dairy Science 01.0905” in this section.
  6. Most of our students need to check ‘no’ in response to the question “Based on Prior Degree?” See our FAQ for details on why.
  7. “Employment Authorization Number” is the left-most number on the front of your EAD (USCIS #: XXX-XXX-XXX)
  8. Yes, digital signatures are fine.

Page 2 (Sections 3 and 4) as well as page 4 (Section 6)

This section must be completed by the employer. Digital signatures are fine.

Page 3 (Section 5)

This can be completed the student and employer together, as it is the training plan.

Page 5 (Evaluations)

Leave page 5, the evaluations, blank, when you are requesting your STEM OPT I-20. It is for later. You will fill this section out later as part of your OPT reporting requirements once your STEM OPT application is approved.

Please visit the Study in the States website for a tutorial on how to complete the Form I-983, or read the I-983 official instructions.

  1. Be sure to carefully read the information on this webpage and our OPT Application FAQs thoroughly before starting the application process.
    • If you still have questions about the application process, please connect with an international advisor via our Advising Options.
  2. Complete the STEM OPT eForm linked above to request the updated I-20. You will need this to submit your online application I-765 Application to USCIS.
    • You will need to upload your completed Form I-983 (pages 1-4) in order to submit your eForm. The I-983 is kept in your file with our office. You will not submit this document to USCIS with your application.
    • You will also need to upload proof of payment of the ISSS fee of $200, which you can pay online. On the Storefront home page, choose “ISSS,” scroll down to the bottom, and click “OPT STEM Extension Student Services Fee.”
  3. An advisor will review your request and email you an updated I-20 recommending you for STEM OPT.

Please note: It can take up to 7-10 business days for our office to process your request once it is received, please plan accordingly.

STEM Optional practical training EXTENSION IMPORTANT INFO

Expand the tabs below to navigate through important information related to STEM OPT Extensions.

If your CSU eID is still active, you can log into your WorldRams account by clicking the STEM OPT Request eForm link at the top of the page.

However, if it has been more than 12 months since you graduated from CSU it is likely that your eID has expired and we will need you to sign into your WorldRams account through the Limited Access Portal in the link below:

  • Step 1: Get your PIN
    • E-mail me my Limited Access PIN
    • You will receive an email with your PIN – when you click the link below to access the form it will ask you for your University Identification Number. This is your CSU Student ID number that begins with an 8.
  • Step 2: Log into the WorldRams Limited Access Portal

If you save or remember this PIN, you will only need to do this process once to access your WorldRams Portal and can use the same PIN to login to your account in the future, such as when you need to submit your OPT Reporting eForm.

What’s the difference between STEM OPT and Post-Completion OPT?

Similarities between OPT and STEM OPT

  1. Both require a special I-20 first.
  2. Both require USCIS Form I-765 to be submitted (different eligibility categories, though–(c)(03)(B) for Post-Completion OPT and (c)(03)(C) for STEM OPT) during a very specific timeframe (the timeframe is different for STEM OPT) to get an EAD.
  3. Both have a work requirement and unemployment to avoid.
  4. Both require employment to be in a position directly related to the student’s field of study and for at least 20 hours/week.
  5. International travel while the I-765 is pending is not recommended.

Differences between OPT and STEM OPT

OPT

  1. No job needed to request.
  2. Any lawful job arrangement is possible, including volunteer roles and freelance.
  3. ISSS does not require any documentation from the employer.
  4. Can combine multiple jobs to get to your 20-hr/week minimum.
  5. Can’t work until you have your EAD.
  6. Reporting is required any time a change occurs, within 10 days.

STEM OPT

  1. A very specific job is required to be secured, as described below and in Form I-983.
  2. You must have a bona fide employer-employee relationship (with you as the employee), and the company you work for must be enrolled in e-Verify.
  3. The employer must work with you to complete Form I-983 and agree to the requirements of it, including evaluation throughout the STEM OPT period.
  4. Positions can’t be stacked to get to the 20 hours/week. All employment arrangements must comply with the I-983 requirements, which means they all must be at least 20 hours/week.
  5. Can work for 180 days as if you already have STEM OPT approval while the I-765 is pending.
  6. On top of the normal reporting within 10 days of any change, there is a check-in style report required every 6 months and an evaluation requirement at the 12-month and 24-month/end of employment marks.

STEM OPT Extension Eligibility

To be eligible for the STEM OPT Extension, you must:

  • be in valid F-1 status while on Post-Completion OPT.
  • not have done STEM OPT twice before.
  • have an eligible employer and position.
  • have filled out pgs 1-4 of the I-983 with that employer and keep up with the extra reporting requirements (such as the pg 5 evaluations).
  • apply within the 90-day period immediately before your EAD expires.
  • have completed a degree in a field on the current STEM list of eligible majors (check your I-20’s CIP Code against this list) in the U.S. within the last 10 years.

Your “Classification of Instructional Programs (CIP) Code” is the number listed underneath your I-20 major in the middle of page 1 on your I-20. It is written in the format XX.XXX.

  1. Look at your last I-20 from ISSS.
  2. If your I-20’s CIP Code is on the linked STEM list, your major is qualified for the STEM Extension.
  3. If your I-20’s CIP Code is NOT on the list, then your major does not qualify for the STEM Extension.
  4. ISSS does not decide which CIP Codes correspond to what academic programs at CSU.
  5. As a reminder, CIP Codes have standardized major names (CIP Code Titles) so as to apply for all the thousands of differently titled but curricularly similar programs across the U.S. It’s okay if the CIP Code Title on your I-20 doesn’t quite match what CSU calls it. For example, CSU has an “Impact MBA” program, but the CIP Code Title for that is “Management Sciences and Quantitative Methods, Other,” so that long name is what would show up on an I-20.

FEES & BUDGETING

The ISSS STEM OPT I-20 fee

  • Note: ISSS charges a $200 one-time fee to issue the STEM OPT I-20. Please plan accordingly.
    • This will not count towards the base USCIS I-765 fee ($470), which you are still responsible for.
  • The ISSS fee allows us to cover the overhead of helping STEM OPT participants throughout their time as STEM OPT participants for two years. The fee is comparable to the $175 immigration services fee we charge to international students for each semester they enroll.

ESTIMATES

  • USCIS has announced an increase in Premium Processing fees, including for I-765 applications, that will go into effect for Premium Processing applications filed Mar 1, 2026 and after.
  • Estimates are subject to change. Always follow USCIS’ fee schedule, as they have changed fees in the past.
  • STEM OPT requires submission of USCIS Form I-765. This form has a $470 fee for STEM OPT (as of Jan 1, 2026).

Someone filing online for STEM OPT would pay ISSS $200 when they request the STEM OPT I-20. Then, after they have the STEM OPT I-20, they’d file USCIS Form I-765 and at the time of submission pay USCIS $470 for their I-765 submission. The total between the ISSS fee and the USCIS fee would be $670.

Note: you’ll also need to budget for a trip to and from Aurora, likely, for your Biometrics appointment following I-765 submission.


PREMIUM PROCESSING

Premium Processing uses Form I-907 in conjunction with your Form I-765. It has a separate fee that is very expensive.

  • For applications submitted with Premium Processing* on or before Feb 28, 2026, the grand total would be $2355 ($470 base fee + $200 ISSS fee + $1685 Premium Processing fee).
  • For applications submitted with Premium Processing* on or after Mar 1, 2026, we have heard that the total for a faster application would increase by $95, for a grand total of $2450 ($470 base fee + $200 ISSS fee + the post-Mar 1, 2026 Premium Processing fee for I-765 of $1780).

Premium Processing guarantees USCIS ‘adjudicative action’ on your case within 30 business days of you adding Premium Processing to your I-765 application.

Actions we know of could be approval, denial, rejection, and RFE (Requests for Evidence) / RFI (Requests for Information).

USCIS says, “If the …application requires the submission of additional evidence or a response to a notice of intent to deny, the 15-, 30-, or 45-day premium processing time period will stop and reset. A new premium processing time period will begin when we receive a response to the request for evidence or notice of intent to deny.”



TIMING

FINDING AN ELIGIBLE STEM OPT JOB

Before you get close to the STEM OPT application window, you will need to check if your employer on Post-Completion OPT is e-Verify and if they will complete the I-983 with you, or else arrange one with a different employer.

Not all positions are eligible for STEM OPT, so many OPT participants who plan to do STEM OPT later on choose to only work with STEM-eligible employers during their Post-Completion period to avoid a last-minute job hunt.

If you do not find a STEM OPT -eligible position by the time your OPT expires, you won’t be allowed to apply for the STEM extension. You will move into the Post-Completion OPT 60-day grace period instead, and you won’t be permitted to work or re-enter the U.S. (unless a transfer out or Change of Level has enabled this process).

Needless to say, since you must have a specific type of job lined up to even apply for STEM OPT, you’ll want to factor in this aspect of job-hunting perhaps as early as your final semester in school or else at the beginning of your Post-Completion OPT period.

Note: it is completely acceptable, so long as you have enough unemployment for it, for your STEM OPT employment to begin on a date later on in the STEM OPT period. An example: Jill’s Post-Completion OPT will end Dec 31, 2025, and her Post-Completion OPT employer was not STEM-eligible, but she has secured STEM-eligible work that begins Jan 30, 2026. It will use up almost half of her new unemployment days allotment, but it’s permitted!

For those who have never been employed in the U.S. and volunteered throughout their OPT period: As of Jul 2025, you cannot apply for the SSN via Form I-765, despite what the I-765 form suggests online. That process has been temporarily suspended. Instead, you’ll need to apply for an SSN on your own after receiving the EAD.

THE I-983 TAKES TIME

  1. To apply for STEM OPT, you have to get a STEM OPT I-20 from ISSS at CSU.
    1. ISSS takes 5-7 days to process
  2. To get a STEM OPT I-20, you have to work with your employer to complete pages 1-4 of Form I-983.
    1. How long will it take your employer to fill out their portion of the I-983? Check with them!

Many students have questions about the Form I-983The I-983 official instructions answer a lot of those questions, as does our tab on the I-983 and our FAQ, but plan for this Q&A time, as well as for whatever amount of time your employer will need to complete their portions. HR often fills out one section while your actual supervisor for the position fills out or guides a different section. That may take up to a month to complete, especially if it’s a busy time in the office.

  • Pages 1-4 must be complete when you request the STEM OPT.
  • Pg 5 is the evaluation which can only be done when you are actually in your STEM OPT period, so leave this blank when applying.

THE APPLICATION WINDOW

The application window opens 90-days out from your OPT expiration. Please check your EAD to see what your OPT expiration date is. 90-days before your OPT expires is the earliest we can create the STEM OPT I-20, and thus the earliest you can request the STEM OPT I-20.

Below is an image to illustrate this timeline. Note that for those who are approved for STEM OPT, there is no 60-day grace period at the end of Post-Completion OPT. There is no gap between the OPT and STEM OPT periods. There will, however, be a 60-day grace period at the end of the STEM OPT, for those who maintain status for the whole 2 years.

This image below illustrates the grace period after the STEM OPT period:

WHILE THE APPLICATION IS PENDING

So long as you are eligible and you file correctly and timely in that 90-day window, you will be permitted to remain in the U.S. and continue working for up to 180 days in a STEM OPT-eligible position, as if you already have approval for STEM OPT.

Remember: once you are in your STEM OPT period, you can only do STEM OPT-eligible work (with the I-983 required for all employment). Your employer may need to update your I-9 with special annotation confirming your continued work authorization. They may need to see your USCIS Receipt Notice. They can reference USCIS’ M-274 Handbook for Employers, specifically the sections about STEM OPT.


AVOIDING UNEMPLOYMENT

STEM OPT has a work requirement, but it adds on 60 more days to whatever remains of your Post-Completion OPT unemployment amount, for a total possible maximum of 150 days of unemployment spread out amongst the three OPT years (90 days for Post-Completion OPT and 60 days for STEM OPT).

For example, by the expiry of his OPT, Bob had used up a total of 52 unemployment days while on Post-Completion OPT. 90-52=38. That means he has 38 unemployment days remaining at the end of OPT. He receives 60 more upon entering his STEM OPT period. 38+60=98. So Bob has a total supply of 98 days beginning on Day 1 of the STEM OPT period and which must last him for his entire STEM OPT period.


REPORTING

STEM OPT participants must report within 10 days of any change, just as they were required to do on Post-Completion OPT. Additionally, during the STEM OPT period, there is a check-in style report required every 6 months and an evaluation requirement at the 12-month and 24-month/end of employment marks. So, 6 months in, 12 months in, 18 months in, and 24 months in, a report will be required, even if nothing changed during the entire 2 years you were on STEM OPT. Please read more about reporting on the OPT Reporting page.


THE END OF YOUR STEM OPT

If you keep your status for your whole STEM OPT period, your work authorization will come to an end after two years. Then you will have a 60-day grace period. During the grace period, you cannot travel and re-enter the U.S. from abroad unless you arrange a SEVIS transfer or a Change of Level within your grace period.

Remember: college admission cycles are often a year out, so you’ll want to carefully plan out these next steps if they are of interest to you. Some STEM OPT participants are selected for H-1B lottery, and can read about Gap-Gap on our FAQ. Put simply, Cap Gap skips the grace period for a more seamless transition between STEM OPT and H-1B. We also send an email to OPT & STEM OPT participants every March on the topic of H-1B and Cap-Gap which answers most questions on the topic.

This image below illustrates the grace period after STEM OPT ends:

Frequently Asked Questions

Optional Practical Training (OPT) comes with important rules, timelines, and responsibilities that every applicant should understand. Please review the FAQs carefully to ensure you’re fully informed before moving forward.

UPDATES:

  • We’ve modified the information on this page about biometrics appointments, given new USCIS procedures.
  • Many STEM OPT applicants who applied with USCIS online have experienced mailing address inaccuracies. To avoid this, you can file Form AR-11 if your address has changed between the I-765 you submitted for Post Completion OPT and the I-765 you will submit for the STEM OPT extension. Try, also, to go into your USCIS account and update your address there, if possible.
  • We’re hearing of delays in STEM OPT applications being processed by USCIS. It’s best to apply early within your filing period, and perhaps start planning to save up for Premium Processing in case the process begins to drag on.
  • USCIS has announced an increase in Premium Processing fees, including for I-765 applications, that will go into effect for applications filed Mar 1, 2026, and after.
