If you filed your STEM OPT extension on time, you can keep working for up to 180 days after your current OPT Employment Authorization Document expires. Working while your STEM OPT is pending is allowed under an automatic extension of employment authorization that begins the day your old EAD expires, provided USCIS received your Form I-765 before that expiration date.1U.S. Citizenship and Immigration Services. Optional Practical Training Extension for STEM Students (STEM OPT) The extension ends the moment USCIS decides your case, whether that decision is an approval or a denial.
How the 180-Day Bridge Works
The rule comes from a STEM-OPT-specific regulation at 8 CFR 274a.12(b)(6)(iv), separate from the general EAD auto-extension that covers other immigration categories.2Study in the States. F-1 STEM Optional Practical Training (OPT) Extension Because it lives in a different part of the regulations, some employers checking the wrong USCIS page conclude the auto-extension doesn’t apply to STEM OPT applicants. It does.
One risk worth naming up front: if day 180 arrives and USCIS still hasn’t decided your case, your work authorization ends even though the application is still pending. You would then have to stop working until the decision comes through. Premium processing, covered below, is the main way to reduce that exposure.
Who Qualifies for the Automatic Extension
All of the following must be true when you file:
- You are in a valid period of post-completion OPT. You cannot file during the 60-day grace period that follows your OPT end date.3Study in the States. Students – Determining STEM OPT Extension Eligibility
- USCIS receives your Form I-765 before your current OPT EAD expires. You can file up to 90 days before expiration, and the application must be submitted within 60 days of your DSO’s STEM OPT recommendation in SEVIS.1U.S. Citizenship and Immigration Services. Optional Practical Training Extension for STEM Students (STEM OPT)
- Your bachelor’s, master’s, or doctoral degree is in an eligible STEM field from a school accredited by a U.S. Department of Education-recognized agency and certified by the Student and Exchange Visitor Program.3Study in the States. Students – Determining STEM OPT Extension Eligibility
- Your employer is enrolled in E-Verify before your STEM OPT begins.1U.S. Citizenship and Immigration Services. Optional Practical Training Extension for STEM Students (STEM OPT)
- You and your employer completed and signed Form I-983, the training plan, and your DSO has it on file.4Study in the States. Form I-983 Overview
Miss any one of these and USCIS will not treat your filing as timely, meaning no 180-day bridge. The most common failure is filing the I-765 after the OPT EAD has already expired, even by a day.
What to Show Your Employer While You Wait
Your expired OPT EAD card, by itself, won’t look valid to an HR reviewer. During the pending period you prove continued work authorization with three documents together:
- Your expired OPT EAD card
- Your Form I-20 showing the DSO’s STEM OPT recommendation
- The USCIS receipt notice (Form I-797C) for your pending I-765
For Form I-9 purposes, your employer records the receipt information and updates Section 2 once the new EAD arrives.5U.S. Citizenship and Immigration Services. Handbook for Employers M-274 – 4.4 Acceptable Receipts If your HR team pushes back because the card on its face has expired, pointing them to the USCIS STEM OPT page usually resolves it.
Rules You Still Have to Follow While Pending
The pending status doesn’t pause your F-1 reporting obligations. Every six months you and your DSO confirm your SEVIS record is accurate, and any changes to your name, address, employer, or employment status must be reported to your DSO within 10 days.6Study in the States. Students – STEM OPT Reporting Requirements Self-evaluations tied to your Form I-983 are due at 12 months and at the end of the 24-month period.4Study in the States. Form I-983 Overview
You are capped at 150 days of unemployment across the entire OPT period. That number is cumulative: any unemployment days from your initial 12-month OPT count against the 150-day total, not on top of it.7Study in the States. Unemployment Counter You must also work at least 20 hours per week for each employer.8Study in the States. STEM OPT Extension Overview
If you change employers while your application is pending, the new employer has to be enrolled in E-Verify before you start, you submit a new Form I-983 to your DSO within 10 days of starting, and you submit a final self-evaluation for the departing employer within 10 days of ending that job.6Study in the States.

Traveling Abroad While Your Application Is Pending
Leaving the country during the pending period is legally possible but risky, and most international student advisors advise against it. The concrete risks:
- If USCIS denies your application while you’re abroad, your F-1 status ends and you cannot reenter in F-1 status. You lose the STEM OPT benefit for that degree level.
- If USCIS issues a Request for Evidence, you generally need to answer it from inside the United States. Missing the deadline means denial.
- If the extension is approved while you’re traveling, you need the physical EAD card in hand to reenter. You cannot file for a replacement card from outside the country.
If you do travel, reentry requires a valid F-1 visa stamp permitting multiple entries, a Form I-20 endorsed for travel by your DSO within the prior six months, and your I-797C receipt notice. A Customs and Border Protection officer makes the final call at the port of entry. The safe move is to stay put until the approved card is in your hands.
When USCIS Decides
If USCIS approves the extension, it issues a new EAD covering your STEM OPT dates, and the 180-day bridge ends on adjudication. Expect roughly two more weeks for the physical card to arrive. Use the new card for future I-9 verification.
If USCIS denies the application, work authorization stops immediately. You then have a 60-day grace period to depart, transfer your SEVIS record, start a new program, or pursue a change of status. You cannot work during that grace period unless you hold separate work authorization.
Premium Processing as a Hedge
USCIS accepts premium processing for STEM OPT extensions on Form I-907.9U.S. Citizenship and Immigration Services. I-907, Request for Premium Processing Service Premium processing guarantees USCIS action within 30 business days. Action means an approval, denial, or Request for Evidence, not necessarily a final decision. If USCIS issues an RFE, the 30-day clock resets when you respond. As of March 2026, the premium processing fee is $1,780, on top of the regular Form I-765 filing fee. It does not speed up production or mailing of the physical EAD card after approval.
For applicants worried about the 180-day window running out mid-employment, premium processing is meaningful insurance. It’s an added cost, but losing work authorization mid-job is almost always the more expensive outcome.
