The STEM OPT to H-1B transition is predictable on paper and messy in real life. Most problems come from timing: an H-1B petition is selected, but the right filing type wasn’t used, the receipt arrives late, SEVIS doesn’t update when expected, or STEM OPT reporting is missed while everyone is focused on the H-1B season. This guide is designed as a practical reference for F-1 students, employers, and DSOs to keep status and work authorization intact through cap season and into the H-1B start date.

Your case may have unique factors (travel, prior status history, pending applications, RFEs, employer changes). Confirm requirements with your DSO and qualified counsel before filing.
Core idea: Cap-Gap is not a “new work permit.” It’s a status/work authorization bridge tied to a cap-subject H-1B petition, SEVIS updates, and the specific way the employer files the case (especially whether it requests Change of Status versus consular processing).
1) Cap-Gap mechanics: what it extends (and what it does not)
Cap-Gap is a regulatory bridge for certain F-1 students moving from OPT/STEM OPT to a cap-subject H-1B. It exists because cap-subject H-1B status typically starts on October 1, while many OPT EADs expire earlier. The bridge works through SEVIS and your Form I-20 record. In most cases, you do not “apply” for Cap-Gap the way you apply for an EAD; it is tied to a properly filed H-1B petition and the SEVIS update flow.
The most common confusion: status extension is not always the same as work authorization. Cap-Gap can extend F-1 status, but whether you can keep working depends on timing and the specific Cap-Gap scenario. Always verify what your DSO sees in SEVIS and what your employer filed on the H-1B petition.
Who typically qualifies
- Cap-subject H-1B petition filed on your behalf for the upcoming fiscal year.
- The petition is timely and tied to the cap process (registration selection followed by filing).
- The case is filed in a way that supports the bridge (most importantly, whether it requests Change of Status).
- Your F-1 record remains in good standing (valid STEM OPT compliance, reporting, and no SEVIS termination triggers).
Decision table: what Cap-Gap can mean for your status and your ability to work
| Scenario you are in | What can be extended | Work authorization reality |
|---|---|---|
| H-1B filed with Change of Status; receipt issued before OPT EAD ends | F-1 status is bridged via SEVIS; Cap-Gap can extend status through the start of H-1B. | Often, work authorization continues during the bridge if the Cap-Gap conditions are met and the record is updated properly. |
| H-1B filed with Change of Status, but receipt comes after EAD end (during grace period) | Status may be extended through Cap-Gap if the case qualifies and SEVIS updates. | Status extension does not automatically mean you may work. Work authorization can stop when the EAD ends. |
| H-1B filed for consular processing (not Change of Status) | Cap-Gap benefits can be limited because the “bridge” concept relies on an in-country status change pathway. | Do not assume you can keep working into the gap; confirm case structure with counsel and your DSO. |
| H-1B denied, withdrawn, or rejected after OPT EAD ended | Cap-Gap ends; you typically fall back to whatever F-1 grace period rules apply (if any time remains). | Work must stop when authorization ends. Plan early to avoid last-minute “cliff” situations. |
In practice, the “bridge” is a coordination exercise: employer files correctly, USCIS issues the receipt, SEVIS updates, and the student stays compliant. If any part of that chain breaks, Cap-Gap becomes uncertain and the risk shifts to the student and employer.
2) STEM OPT compliance while you prepare for H-1B
The fastest way to sabotage the H-1B bridge is to let STEM OPT compliance slip. USCIS and SEVIS treat STEM OPT as a structured program with employer oversight and reporting. If the student record is terminated or falls out of compliance, Cap-Gap is no longer the main problem — the main problem becomes loss of F-1 standing.
STEM OPT I-765 timing (practical rules that matter)
STEM OPT is time-sensitive: your STEM OPT extension application (Form I-765) must be received by USCIS before your current post-completion OPT EAD end date, and the filing window begins up to 90 days before that end date. If you miss the date and enter the 60-day grace period, you generally cannot “rescue” STEM OPT by filing late — and that timing mistake often snowballs into Cap-Gap risk.
What I-983 actually controls
Form I-983 (Training Plan for STEM OPT Students) is not “paperwork for the school.” It is the core compliance document that ties your role, supervision, objectives, compensation alignment, and training evaluation to SEVP rules. DSOs use it to keep the STEM OPT record valid, and audits focus on whether the training plan is real, supervised, and consistent with the employment conditions.
- Before filing STEM OPT Student and employer complete and sign I-983. The DSO issues the STEM OPT I-20 based on that plan.
- 12-month evaluation Complete the first evaluation section on I-983 within 12 months of the STEM OPT start date and submit it to the DSO as required by your school’s process.
- Final evaluation Complete the final evaluation at the end of STEM OPT (or sooner if training ends early) and submit it on time to protect record integrity.
- Material changes Report changes that impact training (employer changes, worksite changes, significant role changes) through the DSO’s process promptly.
Table: the STEM OPT obligations that collide with H-1B season
| Obligation | What triggers it | Common failure mode during H-1B season |
|---|---|---|
| Form I-765 STEM extension filed on time | Approaching OPT EAD end date; filing window opens ~90 days before EAD end. | Waiting for “H-1B selection” first and then realizing the STEM deadline passed or the I-20 issuance window was missed. |
| I-983 evaluations | 12-month evaluation and final evaluation requirements tied to the STEM OPT timeline. | Forgetting evaluations while dealing with receipts/RFEs; late submission creates SEVIS risk. |
| SEVIS reporting / portal updates | Address/employer changes, worksite changes, interruptions, and validation checkpoints as required by your school/SEVP process. | Assuming the employer’s H-1B filing “covers everything” and not updating the student side records. |
| Unemployment tracking | Any gap in qualifying employment counts; limits differ between OPT and STEM OPT rules. | Quietly stopping work because “H-1B is coming” without tracking days and documenting status. |
Bottom line: treat STEM OPT as the foundation. If STEM OPT is clean and timely, the H-1B bridge is mostly coordination. If STEM OPT is messy, Cap-Gap becomes a high-risk improvisation.
3) H-1B season timeline: where the bridge actually breaks
People talk about “the lottery” as if selection solves the problem. Selection is only the start. The bridge depends on: (1) the employer filing the right petition structure, (2) USCIS issuing a receipt, and (3) SEVIS reflecting the Cap-Gap. The risk windows are the weeks when OPT EAD is near expiration, the petition is still pending, and teams assume “it will work out.”
Table: employer/DSO/student actions that prevent “bridge failure”
| What must happen | Who owns it | What to keep as proof |
|---|---|---|
| Correct H-1B filing structure (cap-subject and aligned with in-country strategy) | Employer + counsel | Clear written confirmation of whether the petition requests Change of Status and which start date is requested. |
| Receipt issued in time relative to EAD end date | Employer + counsel; student tracks timeline | Receipt notice details and an internal timeline note tied to the OPT EAD end date. |
| SEVIS updated so Cap-Gap is visible to the school | DSO (SEVIS record) + student provides needed information | Updated I-20 (if issued by the school) and written DSO confirmation of the SEVIS status note. |
| STEM OPT compliance stays clean during the waiting period | Student + employer + DSO | I-983 versions, evaluations, and confirmation that required reporting/validations were submitted on time. |
Practical guardrail: if your OPT EAD end date is close and the petition is not yet receipted, treat it like an emergency coordination task. Cap-Gap is easiest when it is “boring” and documented. It becomes dangerous when everyone assumes SEVIS will sort it out automatically.
4) Top mistakes that break the bridge (and safer fixes)
Most failures follow the same pattern: the employer files an H-1B, everyone assumes Cap-Gap will appear, and the student keeps working without verified documentation. Below are the mistakes that cause the highest number of status/work authorization disruptions in real-world transitions.
5) FAQ + official sources
Do I need to file a separate application to “get Cap-Gap”?
Can Cap-Gap extend my work authorization automatically?
What if my H-1B is denied or withdrawn after my OPT EAD has ended?
What if SEVIS doesn’t update and HR wants proof right now?
Where do I verify the rules without relying on blogs?
