STEM OPT Unemployment Limit: The 150-Day Rule Explained
If you're on STEM OPT, your total unemployment limit extends to 150 days. Here's exactly how it works, what counts, and how to avoid violations.
Quick Answer
STEM OPT recipients are allowed a total of 150 cumulative days of unemployment across both their initial 12-month OPT and the 24-month STEM extension. This is more generous than the 90-day limit for regular OPT.
Quick Answer
STEM OPT students are allowed 150 cumulative days of unemployment across the entire OPT + STEM OPT period (36 months). This is the 90 days from initial OPT plus an additional 60 days from the STEM extension.

STEM OPT vs Regular OPT: Unemployment Comparison
| Factor | Regular OPT | STEM OPT |
|---|---|---|
| Duration | 12 months | 36 months (12 + 24) |
| Unemployment Limit | 90 days | 150 days (90 + 60) |
| Volunteer Work Counts? | Yes (20+ hrs/week) | No — must be paid |
| Employer Requirements | Related to major | E-Verify + related to STEM degree |
| Min Hours/Week | 20 hours | 20 hours (paid) |
| Reporting | Basic SEVP Portal | I-983 + 6-month validations |
Critical STEM OPT Employment Rules
STEM OPT has stricter employment requirements than regular OPT. The key difference: volunteer and unpaid work do not count.
What Stops the Clock on STEM OPT
- • Paid employment ≥20 hours/week at an E-Verify employer
- • Position directly related to your STEM degree
- • Valid I-983 training plan on file with your DSO
- • Multiple employers allowed (each must meet these requirements)
What Does NOT Count on STEM OPT
- • Volunteer/unpaid positions (unlike regular OPT)
- • Working for non-E-Verify employers
- • Jobs unrelated to your STEM field
- • Self-employment without proper registration
STEM OPT Reporting Requirements
STEM OPT students have additional reporting obligations beyond regular OPT. Failure to comply can result in SEVIS termination.
1. 6-Month Validation Reports
Every 6 months, you must confirm your employment details and SEVIS record accuracy with your DSO.
2. I-983 Evaluations
Submit self-evaluations at the 12-month and 24-month marks of your STEM extension.
3. 10-Day Change Reporting
Report any changes to employment (new job, termination, address change) to your DSO within 10 days.
4. Annual Wage Confirmation
Your employer must confirm that your compensation is commensurate with similarly situated U.S. workers.
Frequently Asked Questions
How many unemployment days are allowed on STEM OPT?
STEM OPT students are allowed a total of 150 cumulative days of unemployment across the entire 36-month OPT + STEM OPT period. This includes the initial 90 days from post-completion OPT plus an additional 60 days from the STEM extension.
Does volunteer work count as employment on STEM OPT?
No. Unlike regular OPT where volunteer positions (20+ hours/week) can count, STEM OPT requires paid employment at an E-Verify employer. Volunteer and unpaid work does not stop the unemployment clock during STEM OPT.
What happens if I exceed 150 days on STEM OPT?
Exceeding 150 days of unemployment during the OPT + STEM OPT period can result in SEVIS termination and loss of F-1 status. Your DSO is required to report excess unemployment days to SEVP.
