OPT Extension for STEM Degree Students

A 24-month extension of Optional Practical Training (OPT) is available for certain F-1 nonimmigrant students. This extension is not available to all F-1 students on OPT. This page is designed to help students understand who is eligible for the extension, the steps students must take to apply for the extension, the benefits the extension gives to students and their employers, and the obligations students and employers have during the extension.

Overview of OPT STEM

All F-1 nonimmigrant students can be authorized for 12 months of post completion Optional Practical Training (OPT). OPT can be extended from 12 months to 36 months for F-1 students who have completed a degree in Science, Technology, Engineering, or Mathematics (STEM) and who are employed by employers enrolled in the U.S. Citizenship and Immigration Services (USCIS) E-Verify employment verification program. E-Verify is a free internet-based system which is operated by USCIS, in partnership with the Social Security Administration and determines a new employee’s eligibility to work.

OPT STEM Reporting

This rule has several reporting components. It requires F-1 students on authorized OPT to report changes in the student’s name or address and changes in the employer’s name or address within 10 days of a change in the STEM extension. It requires students every 6 months verify the accuracy of this information with our office. Students are required to submit a formal employer-signed, self-evaluation of the training progress to UC International Services at 12 and 24 month points in the STEM OPT extension period. The self-evaluation will be subject to DHS review and must be submitted within 10 days or completing year one of OPT employment and within 10 days of the expiration of the OPT period.

A new I-983 Training plan is required each time a "material" change occurs in employment. A "material" change includes any change of employer or Employer Identification Number; any reduction in compensation from the amount previously reported on the Training plan that is not a result of a reduction in hours worked; any significant decrease in hours per week that a student works; and any decrease in hours below the 20-hour-per-week minimum required. The new Training Plan must be submitted to UC International Services within 10 days of material changes. The rule requires the employers of F-1 students who have received an extension of post-completion OPT authorization to report to the student’s Designated School Official (DSO) within 5 days of the termination or completion of a student's employment with that employer, if it ends prior to the end of the authorized period of OPT.

Maintaining Continuous Employment

A student who has properly filed Form I-765 for OPT extension prior to the expiration of his or her post-completion OPT EAD is allowed to maintain continuous employment for up to 180 days while USCIS adjudicates the extension request. Application can be made 90 days in advance of the expiration of the post completion EAD. The rule also provides relief for students seeking H-1B specialty worker status and for the employers who wish to hire them.

The status of F-1 students, as well as their work authorization, is automatically extended if a timely-filed H-1B petition has been granted by, or remains pending with, USCIS. This means that anyone whose OPT expires between April 1 and September 30, whose employer has filed an H-1B application with the USCIS, can remain employed as long the petition remains pending (i.e. it is accepted for inclusion in the H1-B lottery) or the petition has been approved for an October 1st start date. However, such students are required to obtain a new I-20 form from UC International Services showing an OPT recommendation that extends the employment beyond expiration of the EAD card. Students will need to provide UC International Services with proof of H-1B receipt or approval in order to obtain the new I-20 form.

OPT STEM Eligibility

In order for you to take advantage of the OPT extension, your degree, as shown on your I-20 form in SEVIS, must be in a degree field that is on the current STEM Designated Degree Program List. STEM refers to degrees in Science, Technology, Engineering, or Mathematics. This means if your degree is in such fields as business, education, the humanities, social sciences or visual and performing arts, you will not be able to apply for an extension of your OPT.

A list of STEM fields can be found here.

E-Verify Employers

In addition, your employer must be enrolled in the E-Verify Employment Verification Program operated by U.S. Citizenship and Immigration Services. Currently, it is estimated that only about 1% of employers nation-wide are registered participants in E-Verify. If your employer is not registered in the E-Verify system, you CANNOT apply for extension of your OPT, even if your field of study is on the STEM degree list. Employers interested in becoming enrolled can visit the E-Verify site at

STEM OPT Employers will be required to provide training and mentoring, assist the student in drafting and signing the formal Mentoring and Training Plan(form I-983) and the self-evaluations, be subject to random site visits, and must sign and submit various attestations. This includes attesting that:

  • The STEM OPT employment terms and conditions(including pay, hours, duties and benefits) are similar to the terms offered to U.S. workers in similar positions.
  • The employer has sufficient resources and training personnel available to provide mentoring and training;
  • The employer will not terminate, lay off, or furlough any full-or part-time, temporary or permanent U.S. workers as result of the STEM OPT employment; and the opportunity benefits the students in attaining his/her training objectives.
  • The employer must assist the student with completion of the I-983 Training plan for STEM OPT students and sign the student's evaluation on an annual basis.
  • The employer is required to remain in good standing with E-verify while employing students on STEM OPT.
  • Employers must understand that this rule gives DHS the discretion to conduct site visits with 48 hours notice. If a complaint has been filed or there is evidence of noncompliance with the STEM OPT regulations, DHS may conduct the visit without notice.

Unemployment During OPT

DHS regulations define the period of an F-1 student’s valid status as the time the student is pursuing a full course of study or is engaged in authorized post-completion Optional Practical Training, plus a 60 day grace period. The DHS has established an aggregate maximum period of allowed unemployment of 90 days for students on 12-month OPT. Students who qualify for and receive the 24-month OPT extension can be unemployed for an aggregate of 150 days.

Volunteer (unpaid) employment while on post-completion OPT does not accrue unemployment time provided the volunteer work is for 20 hours per week or more. Volunteer work is not available during the 24-month STEM extension. Unemployment does not count during pre-completion OPT.

This particular part of the rule also puts responsibility on students to keep UC International Services up to date with the name and address of your OPT employer. Unless we have the SEVIS system updated with the name and address of your employer, you will be accumulating unemployment time in SEVIS. Once you have reached the 90 or 150 day maximum your F-1 status will be terminated.

For those of you currently looking for employment, please notify UC International Services with the name and address of your employer once employment is secured. If you don’t secure employment within the 90 days of beginning your OPT, you will be expected to depart the U.S. or otherwise take steps to maintain proper F-1 status (get a new I-20 to start a new program of study).

Issues related to obtaining multiple STEM OPT authorizations or using STEM OPT employment for a degree obtained in the past

  • STEM students will now benefit from the ability to earn a second qualifying STEM OPT period by obtaining a STEM degree at a higher educational level.
  • The rule permits an F-1 student participating in a 12-month period of post-completion OPT based on a non-STEM degree to use a prior eligible STEM degree as a basis to apply for a STEM OPT extension.
  • The STEM degree must have been completed in the U.S. and have been obtained within the past 10 years.
  • Students wishing to obtain a STEM OPT employment period based on a degree obtained in the past must apply through the DSO at school the student most recently attended.
  • Students will not be able to obtain back-to-back STEM OPT extensions. A STEM OPT extension can only be granted as an extension of a regular OPT period.

H-1B Cap-Gap Relief

Perhaps the most significant part of the OPT regulations relates to what is called "cap-gap" relief. This rule extends the status and work authorization of any F-1 student whose OPT EAD expires between April 1 and September 30 if the student is the beneficiary of a timely-filed H-1B petition requesting an employment start date of October 1 of the following fiscal year. This rule applies to all students on OPT, not just STEM students. The extension of duration of status and work authorization automatically terminates upon the rejection, denial, or revocation of the H-1B petition filed on the student's behalf.

Students are required to obtain a new I-20 form from UC International Services showing an OPT recommendation that covers this "cap-gap" period. Students will need to provide UC International Services with proof of H-1B receipt or approval in order to obtain the new I-20 form. Cap-gap students can apply for the OPT extension even if the current OPT has expired, but the student would need to have the employer request a withdrawal of the approved or pending H-1B petition before 10/01. Students need to supply evidence that a withdrawal request has been made.

OPT STEM Extension Authorization

  5. Completed I-765 Form. USCIS has amended form I-765 to add, among other things, a revised question #16 and a new question #17. Question #16 asks for the code that reflects the type of OPT you are requesting. You should put (c)(3)(C) as the code. Question #17 asks students to identify the degree you have received. You will need to attach a copy of your transcript showing degree completion and the field of study. It will also ask you to provide the name of your employer as listed in E-Verify and their E-Verify company ID number or, if the employer is using a Designated Agent to perform the E-Verify queries, a valid E-Verify Client Company I.D. number. You will need to get this information from your employer.
