STEM OPT Extension

Qualified students on Optional Practical Training (OPT) in one of the designated STEM fields can apply for a 24-month extension of their OPT. Click here to view a recording of a 24-month STEM OPT webinar hosted by OIS.

Students must file an application with USCIS to apply for the STEM extension of OPT. During the STEM extension period students may only work for employers who are enrolled in the E-verify system and the employer must agree to update OIS within 5 business days when the student leaves or the employment is terminated.

E-verify is a system that shares information between the Social Security Administration and the Department of Homeland Security to verify that a potential employee is eligible to work in the United States. During the STEM extension students may change employers or work for multiple employers, provided that all employers are enrolled in the E-verify system. Not every employer is enrolled in E-verify and there is not an official list of E-verify employers. Therefore, students will need to confirm this information with the employer directly. If the employer has questions about the E-verify system, please refer them to the USCIS website or their human resources professional.

During the STEM extension students are required to update OIS within 10 days of any change in their legal name, immigration status, employment status, or residential address. The process of reporting these changes is described below in the STEM Extension Reporting Requirements. Students must also report to OIS every six months, even if their information has not changed, using the online OPT Employment Validation Form. Please see the FAQ page about the STEM extension and contact OIS if you have any questions.

STEM Eligibility Requirements

  • Student must have completed a degree program in a STEM field, which currently serves as the basis for the student’s current post-completion OPT (a previous STEM degree may be used under certain conditions – see below for more details).  This means that the CIP code of the student’s major must appear on the STEM Designated Degree Program List approved by the Department of Homeland Security (DHS) as of May 10, 2016. The CIP code is used to standardize majors and is what a student should use to determine if his or her major appears on the STEM list. The major’s CIP Code is listed on a student’s current I-20 (first page, “Program of Study” section). If your major’s CIP Code is not on the above-referenced STEM List approved by DHS and you don’t have a qualifying previous degree (see below), you will not be eligible for STEM OPT – no matter how closely your major is related to other programs that are on this list
  • Student must be engaged in an approved post-completion OPT in order to apply for the STEM extension. Student may not file a STEM OPT application sooner than 90 days before the student’s current OPT expiration date.
  • Student must have a job offer from an employer enrolled in E-verify.
  • Students may apply for the STEM OPT extension based on either their current degree or on a previous STEM degree earned at an accredited and SEVP-certified U.S. educational institution. That previously obtained degree must have been conferred within the 10 years preceding the date when OIS recommends the student for STEM OPT.
  • F-1 students are eligible for one 24-month STEM extension per qualifying degree.  Students may become eligible for an additional 24-month OPT STEM extension by completing another degree at a higher level for a total of two 24-month STEM extensions per lifetime. Degrees earned outside of the U.S. cannot be considered for a STEM OPT extension application.

Types of Employment

During the STEM extension period, students must be employed for at least 20 hours per week by an E-Verify employer in a position directly related to their field of study. Types of employment that are allowed during the STEM extension period are:

  • Multiple employers. Students may work for more than one employer, but all employment must be related to the student’s most recently completed STEM degree program and all employers must be enrolled in E-Verify. Moreover, each STEM OPT employment must be at least 20 hours per week. For more details, please review the STEM Extension Reporting Requirements section below (under “Changing Employers or Adding a New Employer”).
  • Paid employment. As of May 10, 2016, unpaid internships and volunteer work are no longer eligible employment opportunities for the STEM OPT extension. Similarly, students cannot represent themselves as both employer and employee on the I-983 form, meaning self-employment is also not allowed.
  • Bona fide employer-employee relationship. To be eligible to employ a STEM OPT student, an employer must have a bona fide employer-employee relationship with the student. The employer that signs Form I-983 must be the same entity that provides the practical training experience to the student. Moreover, a STEM OPT student must be supervised by the employer’s own personnel. Please review the “STEM OPT Employer Requirements and Responsibilities” of this USCIS webpage for more details.

Please note: it is the student’s responsibility to maintain documentation for each job held during the OPT period. It is recommended that students obtain proof that the position is/was related to the STEM field that the student completed, duration of the position and contact information for the manager/supervisor

STEM Extension Application Process – Step I: Request a new I-20 for STEM OPT from OIS

Before sending the STEM OPT application package to USCIS, students need to receive a new Form I-20 with the STEM OPT recommendation from OIS. In order for OIS to issue the STEM OPT I-20, student must upload the following documents to the STEM OPT Upload Center:

  • Copy of previous EAD(s)
  • Copy of Form I-983 (pages 1-4) completed and signed by student and employer. (Check the Instructions on Completing the Form I-983.) Form I-983 pre-filled with NC State’s information is available on our Forms page. If you are applying for STEM OPT with NC State as your employer, please use Form I-983 for students applying for STEM extension as NC State University’s employees available on our Forms page.
  • Make sure the information in your SEVP Portal account is up to date.

Please use your NCSU email credentials to access the form. If you’re using Chrome as your internet browser, please make sure you are logged in under your NCSU Gmail account.

OIS issues a new Form I-20 with the STEM extension recommendation and a new travel endorsement page. You will need a copy of this document to be included as part of your application to USCIS. When your I-20 is ready, you will receive an email from OIS with an attached cover letter that will include details for assembling and mailing the STEM OPT application to USCIS, as well as reporting requirements. If you’re unable to pick up the I-20 from our office, you can send us a shipping label and we will arrange the delivery of the document to your location.

Please allow up to 10 business days for processing and issuance of the new I-20.

STEM Extension Application Process – Step II: Mail the STEM OPT Application to USCIS

Student should mail the application to the appropriate USCIS office before the student’s current EAD expires, but no earlier than 90 days prior to the current EAD expiration date and no later than 60 days from the date the I-20 with the STEM OPT recommendation was issued by OIS (as indicated by the Designated School Official’s signature date on page 1 of the I-20).

USCIS requires that the STEM application include:

  • Form G-1145 (optional). Use most recent version available at This form is for students who wish to receive electronic notification that their application has been accepted.
  • Form I-765 (original, signed). Use most recent version available at Please review the OIS Guidelines for Completing Form I-765. Important Note: Among other things, you will need to indicate your employer’s E-Verify number on this form. Many students confuse E-Verify number with Employer Identification Number (EIN) that they enter on their Form I-983. E-Verify and EIN are not the same number! Make sure you obtain a correct E-Verify number from your employer before you fill out this form. 
  • Check or money order for $410 stapled to I-765, made payable to U.S. Department of Homeland Security.
  • Two identical color passport-style photographs (2″ x 2″) taken within 30 days of filing date. Write your full name and A-Number (same as USCIS #, which should be listed on your current EAD card) using a pencil or a felt pen on the back of each photo. Paperclip the photos to the I-765. For specific photo requirements, please refer to the I-765 Instructions available at Make sure you don’t wear glasses when the photo is taken!
  • Copy of the new I-20 with the STEM OPT recommendation from OIS (sign your I-20 before photocopying and leave a copy with OIS).
  • Copy of your current and previously issued EAD(s).
  • Copy of diploma and/or transcripts clearly showing graduation in a STEM field.  If diploma does not list your field/major, you must include transcripts.  Unofficial transcripts are fine.  USCIS does not need sealed, official transcripts.
  • [Highly recommended but not required] Copy of the I-20 with the initial OPT recommendation from OIS. We also recommend that you include copies of all other previously issued I-20s.
  • [Highly recommended but not required] Copy of an offer or employment verification letter from a qualified E-Verify Employer indicating job title, job description, and work location.
  • Copy of most recent F-1 visa.
  • Copy of passport ID and expiration page (valid at least 6 months into the future).
  • Other forms or documents as may be recommended by your attorney or HR representative.

Use this list of USCIS lockbox facilities to determine where to mail your application.

Information regarding employment authorization is subject to change. Students should confirm the application requirements, fees and process with USCIS. For the most up to date instructions regarding the I-765 please see:

If the application is approved, USCIS will issue a new EAD with the STEM OPT dates. Review the EAD card for accuracy and provide a copy to OIS. If you fail to provide a copy to OIS, you may lose your status and employment authorization.

STEM Extension Application Process – Step III: USCIS Processing

The following information should be kept in mind regarding USCIS processing of the STEM OPT application.

  • USCIS processing time is approximately 90 days from the day USCIS receives your application.
  • Within 2-3 days of USCIS receiving your application, you should receive a text message or email, if you included the G-1145 form with your application.
  • Within about 2-3 weeks you should receive a paper receipt notice from USCIS at the address listed on the I-765 indicating that your case has been accepted for processing.  If you do not receive this within 30 days, you should contact USCIS as there may be an issue with the mailing address you indicated on the I-765.
  • The paper receipt notice documents that your case has been accepted for processing by USCIS. Once your case is in process, your F-1 status and work authorization are automatically extended for a period of 180 days following the expiration date of your current EAD. The expired EAD presented together with the Form I-20 issued for the STEM extension and the Receipt Notice from USCIS will be sufficient to prove your employment authorization until you receive the new EAD.
  • Once your case is approved, you will receive the I-797 Approval Notice and the EAD (separately).
  • If USCIS needs more information or documentation to approve your case, you will receive a Request for Evidence (RFE).  If you receive an RFE, please contact OIS immediately.

USCIS does not allow applicants to pay a fee for expedited processing and guaranteed adjudication by a certain date.  Rather, USCIS accepts requests for expedited processing of petitions filed in a timely manner based on certain criteria. Students may follow the instructions on the USCIS web page to determine if you meet the USCIS criteria for expedited processing and to complete an expedited processing request. OIS is not involved in the processing of any petitions filed with USCIS and any inquiries regarding the expedited processing request need to be sent to USCIS.

Students may also contact USCIS directly to ask questions regarding pending applications.  USCIS offers a request for inquiry regarding a pending petition. Students may follow the instructions on the USCIS web page to request an inquiry and update from USCIS regarding  their pending petition. OIS is not involved in the processing of any petitions filed with USCIS and any questions regarding the inquiry process need to be sent to USCIS.

STEM Extension Application Process – Step IV: Provide Copies of your EAD

  • When you receive the EAD, provide a copy to your employer.You must also submit a copy of your new EAD to OIS through the STEM OPT Upload Center. OIS requires a copy so that your OPT extension and EAD can be verified in SEVIS.
  • If you fail to provide OIS a copy, you may lose your status and employment authorization.

STEM Extension Reporting Requirements


  • Updating Residential Address in MyPack (within 10 days of move). Just like during the regular 12-month OPT, during the STEM extension you are required to update your residential address in MyPack (in the “Home/Mailing” and “SEVIS Local” fields) within 10 days of move. The latest address from the “SEVIS Local” field will be automatically copied to your SEVIS record. If you have registered an SEVP Portal account, please also update your address there.
  • STEM OPT Validation (every 6 months). Every six months STEM OPT students are required to confirm their employment and address information. You must report to OIS 6 months, 12 months,18 months, and 24 months after the start of your STEM OPT extension by submitting the online OPT Employment Validation Form. The window for reporting a 6-month STEM OPT validation opens 15 days before the reporting date (i.e. the 6-month mark) and is due within 10 days of the reporting date.

Use our STEM OPT CALCULATOR to calculate your reporting windows.

  • Annual Evaluations (every 12 months). Every 12 months you must submit to OIS an annual self-evaluation on page 5 of Form I-983 on the progress of your training experience, which must be signed by you and your employer. The section titled “Evaluation on Student Progress” must be submitted for the first 12 months of STEM OPT and the section titled “Final Evaluation on Student Progress” must be submitted at the end of STEM OPT. The self-evaluations are due within 10 days of the reporting date. Please use the STEM OPT Upload Center to submit your annual evaluations.

Use our STEM OPT CALCULATOR to calculate your reporting windows.

  • Changing Employers or Adding a New Employer (within 10 days). You must notify OIS within 10 days of changing employers or adding a new employer by submitting the following documents through the STEM OPT Upload Center (please select “Report change of STEM OPT employer” as the reason of submission):

SEVP Portal:

On March 23, 2018, DHS’s Student and Exchange Visitor Program (SEVP) has launched the SEVP Portal. The SEVP Portal is a tool that F-1 student on OPT or STEM OPT extension can use to report changes to their home/mailing address, telephone number and employer information. Please review the information and links related to the Portal here:

The use of the Portal is not mandatory, but highly recommended by SEVP and OIS.

STEM Extension I-983 Training Plan and Evaluation Requirements

All prospective STEM OPT students and employers are required to complete a Training Plan (Form I-983) at the start of employment to establish expected outcomes and learning objectives. This reporting and oversight requirement establishes the extended OPT period as an integral piece of an academic training experience. Students will need to review Form I-983 every 12 months throughout the STEM OPT experience to self-assess progress and performance. The training plan, or Form I-983, can be found here:  A Form I-983 pre-populated with NC State University’s School SEVIS Code and DSO Contact Information can be found on OIS’s Forms for Current Students page.  Make sure to read the Instructions on Completing the Form I-983. If your employer has questions about this requirement, please refer them here:

If you have further questions, talk to your current employer or a potential new employer about the new I-983 Training Plan requirements. DHS has a wealth of information on their website for employers here: The employer should review the new requirements and work with you to start preparing the I-983.

Days of Allowable Unemployment

Students who are granted the 24-month STEM extension of OPT can have up to 150 cumulative days of unemployment during the 36-month OPT period (the original 12-month OPT plus the 24-month STEM OPT extension).
