  • Be in F-1 status
  • Be currently working in a period of post-completion OPT
  • Have a bachelor’s degree or higher degree in an eligible STEM field
    • You may be eligible use a prior STEM degree earned in the U.S. for this requirement; to use a prior STEM degree, you must:

      • Have received your prior, qualifying STEM degree in the U.S. within 10 years of applying for the STEM OPT extension.
      • The qualifying STEM degree must be on the Department of Homeland Security’s STEM Designated Degree Program List at the time you submit your STEM OPT extension application (rather than at the time you received the degree).
  • Have a paid job offer that meets the following requirements:
    • The job is with an employer enrolled in the USCIS E-Verify program. Double-check with your employer to see if they are enrolled in E-Verify; sometimes the USCIS E-Verify database is not correct.

    • The job offers at least 20 hours of work per week
    • The job will provide formal training and learning objectives directly related to your qualifying STEM degree
  • Be able to complete the I-983 Training Plan with your employer

Employment Requirements During the 24-month STEM OPT Extension

You must work at least 20 hours per week for an employer that a) participates in the E-Verify program and b) agrees to follow all the employer requirements in the 24-month STEM rule.

Unlike the 12 month OPT, volunteer/unpaid work or self-employment is not permitted under the 24 month STEM OPT Extension regulation.

Please review the new guidance about acceptable types of activity during the 24-month STEM OPT Extension that is substantially different than the 12 month OPT and past guidance for the STEM Extension.

When to Apply

Students with a STEM degree and currently in the 12-month OPT period:

  • USCIS must receive your STEM OPT extension application before your current 12-month OPT EAD card expiration date.
  • Apply as early as 90 days before your current 12-month OPT EAD card expiration date.
  • Take into consideration:
    • ISS needs 7-10 business days for processing your new I-20.
    • Allow sufficient time to mail your application to USCIS.

How to Apply

If your 12-month OPT expires on or after June 8, 2018, wait until March 1 to request your STEM OPT extension I-20 from ISS. The instructions below will change on March 1.

Students with a STEM degree and currently in the 12-month OPT period:

STEP 1: Complete the ISS 12-Month OPT Report Webform

Complete the ISS 12-Month OPT Report webform. You might have already completed this during your 12-month OPT period. Please complete the webform again. ISS must ensure the 12-month OPT information in your SEVIS record is accurate and updated before processing your STEM OPT I-20 request.

STEP 2: Complete and submit your STEM OPT Extension I-20 Request to ISS

  1. Gather and complete the following documents
  • I-983 Training Plan (see ISS Tips for Form I-983)
    If you will apply for the 24-month OPT extension based on employment at UW, see these tips from International Scholars Operations for completing the I-983 Training Plan for UW employment.
  • Completed I-765 Form (download I-765 form completion guide with proofreading tips)
    • It is okay to leave the E-Verify field blank in the I-765 Form in this situation. ISS maintains a list of employers who do not share the E-Verify number with university officials because the employers will submit the OPT extension application on behalf of their employees. If your employer is not on the list, your ISS adviser might contact you to ask for a confirmation letter from your employer that states their policy.
  1. Submit the online STEM OPT Extension I-20 Request to ISS:

    Request STEM OPT Extension I-20

  1. Allow 7-10 business days for processing. An ISS adviser will review your application and issue a new, updated I-20 with a STEM OPT Extension recommendation printed on the back page.

STEP 3: Pick up New I-20 and prepare your application

  1. When you receive an email from ISS, pick up your new STEM OPT Extension endorsed I-20
    • Sign the new I-20 at the bottom of page 1.
    • Photocopy after signing; you will send the photocopy, not the original I-20
  2. Gather the following documents
    • Copy of Form I-20 with your signature and STEM Extension endorsement by your DSO (ISS adviser) (must arrive at USCIS within 60 days of issuance)
    • Form I-765 (Be sure to include your employer’s name as listed in E-Verify and E-Verify Company Identification Number or valid E-Verify Client Company Identification Number)
    • Copy of your transcript
    • A copy of Form I-94 (which can be obtained at
    • A copy of your current EAD card (front and back)
    • 2 passport-style photos. Lightly write your name and I-94 number on the back of each photo. (Review number 2. C on page 8 of the “Required Documentation” section of USCIS photo instructions)
    • Form I-765 filing fee paid by money order, personal check, cashier’s check, or credit card using Form G-1450, Authorization for Credit Card Transactions. If you pay by check, you must make your check payable to the U.S. Department of Homeland Security.
    • Completed G-1145 Form (optional; it signs you up for email/text message notification of your application’s arrival at USCIS)
    • Note: the I-983 Training Plan does not need to be submitted to USCIS (unless USCIS requests a copy during STEM OPT extension processing). You should keep a copy of the plan for your own records, and ISS also keeps a copy.
      Also, USCIS I-765 filing instructions (both general and STEM OPT) do not require copies of previous I-20s, passport biographical page, nor F-1 visa page. You may include these copies if you want to, but they are not required.

STEP 4: Mail your application to USCIS:

Mail the documents listed in item 2 from STEP 3 to:

  • For U.S. Postal Service (USPS) Deliveries

PO Box 21281
Phoenix, AZ 85036

5. If I have a dual major, can I qualify for the 24-month extension based on one of the degree programs?

Yes, if one of the degrees is on the STEM Designated Degree Program List and any job worked while on the extension is related to your STEM degree.

6. Can I qualify for the 24-month extension based on my minor or certificate program?


7. When does my 24-month extension of OPT start?

If you have properly filed for a 24-month STEM extension, the period of extension starts the day after the expiration of your original OPT period.

8. Can I work with an expired EAD while my 24-month extension is pending?

Yes. Your work authorization is automatically extended for up to 180 days while the 24-month STEM extension application is pending. There is no interim documentation of the extended authorization. If your employer needs information about what documents to collect as proof of extended work authorization, please refer to them to U.S. Citizenship and Immigration Services I-9 Central.

9. Can I travel outside of the U.S. if my original EAD expires and my 24-month extension is still pending?

Yes, your EAD is considered extended for up to 180 days while your STEM OPT extension application is pending with USCIS. During that period, you can travel outside the U.S. even if your previous EAD is expired.

For more information about what documents to carry, and citations for this rule, see scenario #4 in our “Travel and OPT” section.

10. Do I need to use the ISS address on the I-765?

No, you are not required to use the ISS address on #3 of I-765 form. However, be sure to provide an accurate and valid address for at least 4 months into the future so you can receive your EAD card. The post office will NOT forward OPT mail. If you might change your address while your OPT application is pending, consider renting a post office P.O. Box or using a friend’s address or ISS address. 

11. Can I change employers while the 24-month extension is pending?

Changing employers while your 24 month STEM OPT Extension is pending can be risky because the regulations do not contemplate such situations.

If you must change employers, submit a new I-983 and provide the E-verify number to Then complete a new OPT Reporting Form. Regulations state that employment changes must be reported within 10 days.

Note: the new employer information will not match the employer information in the STEM OPT Extension application you submitted to the USCIS. There is currently no immigration guidance about how to resolve this conflict. Some students have mailed an additional updated application with a letter explaining their situation. However, errors may occur with additional updated applications to USCIS. USCIS has rejected a few of such applications because they simply think it’s a new application missing a filing fee. Another option is to provide the updated I-983 Training Plan, E-Verify number, and OPT employment reporting to ISS, but not mail any additional documents to USCIS unless they send you a “Request for Evidence” (RFE).

We hope to receive new guidance soon from USCIS about how to proceed in these situations.
