Executive Summary
- OPT employees work on a time-limited EAD card that expires. There are no automatic extensions unless the employee qualifies for a STEM OPT extension and files on time.
- STEM OPT adds 24 months of work authorization. The employer must be enrolled in E-Verify and must complete a training plan (I-983) with the employee before the extension is filed.
- HR is responsible for I-9 re-verification when the EAD expires. If you miss it, the employee is working without valid documentation.
- There are multiple deadlines to track: the OPT EAD expiry, the STEM filing window, the 180-day auto-extension period, and the cap-gap window if the employee is in an H-1B lottery.
What OPT is
OPT stands for Optional Practical Training. It allows F-1 international students to work in the United States in a job related to their field of study after completing their degree.
Standard OPT gives the employee up to 12 months of work authorization. That authorization is issued on an Employment Authorization Document (EAD card). The employee cannot work without it in hand.
OPT is not sponsored by the employer. The student applies through their university's Designated School Official (DSO), and USCIS issues the card directly to the student. Your company does not file anything for standard OPT. But you do have I-9 responsibilities, and the EAD expiration date is your clock.
The EAD card and the I-9
When you hire an OPT employee, they present their EAD as a List A document for I-9 purposes. The card shows an expiration date. That date matters.
Per USCIS guidelines (M-274, the Handbook for Employers), employers are required to re-verify the employee's work authorization before the EAD expires. You do this in Supplement B of the I-9. If the EAD expires and you have not re-verified with a new, valid document, the employee is not authorized to work. Consult your I-9 compliance advisor if you are unsure about your specific situation.
The category code on the EAD tells you what type of OPT you are looking at:
- C(3)(A): Pre-completion OPT (student is still enrolled)
- C(3)(B): Post-completion OPT (student has graduated)
- C(3)(C): STEM OPT extension
On the physical card, the parentheses are dropped and it will read C03A, C03B, or C03C. Knowing the difference matters because the re-verification path and timing are different for each.
When OPT ends: the STEM extension
If your employee has a degree in a STEM field (science, technology, engineering, or mathematics) and their degree falls on the USCIS STEM Designated Degree Program List, they may qualify for a 24-month STEM OPT extension. That brings their total work authorization to 36 months.
This is where most HR teams fall short. The STEM extension is not automatic. The employee must file before their current OPT EAD expires, and you, as the employer, have two requirements:
1. Your company must be enrolled in E-Verify. STEM OPT employees can only work for E-Verify employers. If your company is not enrolled, the employee cannot get the STEM extension and cannot continue working for you past their 12-month OPT expiration. Check your E-Verify status before the employee starts their STEM OPT application.
2. You must complete a training plan (I-983). Form I-983 is the Training Plan for STEM OPT Students. It documents the skills the employee will develop and the learning objectives tied to their role. The employee cannot file the STEM extension without it. The form needs to be completed and signed by both the employee and a company representative.
Once the STEM OPT application is filed (before the original EAD expires), the employee can continue working for up to 180 days while USCIS processes the new EAD. Do not re-verify during this window. The combination of the expired EAD and the I-797 receipt notice is sufficient documentation.
The unemployment rules
F-1 students on OPT are subject to limits on how many days they can go without employment. Per USCIS policy:
- Regular OPT: up to 90 cumulative days
- STEM OPT extension: up to 150 cumulative days total, counting across both the regular OPT and STEM periods combined
HR does not track these days and is not responsible for doing so. The student's school (Designated School Official, or DSO) maintains the official count through the SEVIS system. Students are required to report any changes in employment to their DSO within 10 days.
What this means practically: if your company ends an OPT employee's employment, it is worth letting the employee know that any gap before their next role starts counts toward their limit. This is useful context to share, especially if the departure is a layoff or a role elimination where the employee may be job searching for a period of time. Consult an immigration advisor before taking any employment action involving an OPT or STEM OPT employee.
The filing window for STEM OPT
The employee should apply for the STEM OPT extension no later than 90 days before their regular OPT EAD expires. Earlier is better.
Here is why this matters to you: the I-983 Training Plan has to be completed before the application goes in. If you are slow to fill out your section of the form, you can push the employee past the safe filing window. Build a lead time into your internal process. When an OPT employee tells you they want to apply for a STEM extension, treat the form completion as a two-week task, not a someday task.
Cap-gap: what it is and when it applies
If your OPT employee is selected in the H-1B lottery and has an October 1 start date, their F-1 status and OPT work authorization are automatically extended through April 1 while USCIS processes the H-1B petition.
This is called cap-gap. It was updated in January 2025. The extension used to run through September 30, but it now runs through April 1 of the following year to bridge the gap between OPT expiration and H-1B start.
During cap-gap, the employee can continue working. The documentation for I-9 re-verification is the expired EAD plus the I-797 approval notice for the H-1B petition. Do not terminate an employee or stop payroll because the EAD card has expired. Verify the cap-gap status first.
The tracking problem
OPT employees have more date-sensitive milestones than almost any other visa category your company manages:
- OPT EAD expiration date
- STEM OPT application deadline (90 days before EAD expiry)
- STEM OPT 180-day auto-extension period
- I-983 completion deadline
- H-1B cap-gap window (if applicable)
- Cap-gap end date (April 1)
- Re-verification due date on the I-9
Most HR teams track these in spreadsheets, which means someone has to remember to update the spreadsheet. When a hire is made, no one is thinking about 12 months from now. When the deadline arrives, no one is sure who is responsible for the re-verification or whether the employee filed for the STEM extension on time.
Frequently asked questions
Can my company sponsor OPT? No. OPT is authorized by USCIS based on the student's program of study. You hire the employee once they have the EAD in hand. You do not petition for OPT.
Does the OPT EAD auto-extend? No. Not unless the STEM extension is filed on time. If the EAD expires and no STEM extension is pending, the employee cannot work.
What if we are not enrolled in E-Verify and we want to hire a STEM OPT candidate? You would need to enroll in E-Verify before the employee applies for the STEM extension. Enrollment takes a few days. Do not wait until the week before the filing deadline.
Can the employee work during the 180-day auto-extension period? Yes. As long as the STEM OPT application was filed before the original EAD expired, the employee can continue working while the new EAD is being processed. The I-797 receipt notice serves as the documentation.
What if we let the EAD expire without re-verifying? You have a problem. The employee cannot legally work, and continuing to employ them creates an I-9 compliance issue. Work with an immigration advisor to understand the corrective steps.
