The thing most students get wrong about STEM OPT is assuming the risk sits with them. It usually doesn't. Most denials and most Requests for Evidence are triggered by something the employer did or failed to do — which means the checks that matter happen before you file, and they are checks on your company.

The numbers
Denial rate, FY2023 8.7%
Applications receiving an RFE ~15%
Grace period if denied None

Roughly one in twelve is denied and one in seven draws an RFE. That is high enough that "it'll probably be fine" is not a strategy.

The top causes, in order

1. E-Verify enrolment gaps. Your employer must be enrolled in E-Verify. A gap of more than 30 days before your OPT start date triggers problems. This is the single most common employer-side failure, and students almost never check it.

2. Missing signature on page 2 of the I-983. Page 2 carries the employer's certification. An unsigned or incompletely signed page 2 is a straightforward denial. Check every signature block, not just the obvious one.

3. Job duties that don't match your degree's CIP code. The training plan must describe work related to your STEM field as classified. A computer science graduate whose I-983 describes general business analysis is a mismatch — and the mismatch is judged against the CIP code on your I-20, not against how you'd describe your own job.

4. Wage below the prevailing wage determination. New in 2026: filing an I-983 with a salary below the applicable PWD is now drawing RFEs. Check the PWD for your role and location before your employer completes the form.

5. SEVIS reporting gaps. Missed reporting obligations surface at adjudication.

6. Filing outside the 90-day window. The application must be filed within 90 days before your OPT expires. Outside that window it fails on timing regardless of merit.

Why the employer is the weak point

USCIS data shows the majority of RFEs come not from student documentation gaps but from employer E-Verify non-compliance or CIP code mismatches.

This creates an awkward dynamic. You are the one whose status depends on the filing, but the failure modes sit with an HR department that may have done this once before, or never. Smaller employers and startups are disproportionately represented in these problems.

Practical consequence: you have to audit your own employer. Before the I-983 is completed:

  • ☐ Confirm the company is currently enrolled in E-Verify, and ask when enrolment started
  • ☐ Check there is no gap of 30+ days before your OPT start date
  • ☐ Read the training plan against your degree's CIP code yourself
  • ☐ Verify every signature block on page 2 is complete
  • ☐ Check the offered wage against the prevailing wage determination
  • ☐ Confirm you are inside the 90-day filing window

Nobody else is going to run that list on your behalf.

There is no grace period

If the extension is denied, there is no cushion. Failure to provide acceptable documentation results in denial with no grace period, which means status problems begin immediately rather than after a buffer.

That is why the pre-filing audit matters more than the appeal strategy. Fixing an I-983 before submission takes an afternoon. Recovering from a denial is a different order of problem, and usually needs a lawyer.

If you get an RFE

An RFE is not a denial. It is a request for something specific, and it has a hard deadline.

  1. Read exactly what is being asked. RFEs are narrow. Answer that question, not the general topic.
  2. Most are employer-side, so the response usually needs your employer's cooperation quickly. Tell them the deadline the day you receive it.
  3. Do not file a partial response hoping to supplement later. There is one bite at this.
  4. Consider a lawyer if the RFE concerns CIP code alignment — that is an argument about classification, not a document you can simply produce.

How this fits the wider picture

Refusal rates across the F-1 to H-1B chain Four stages. F-1 visa refusal for Indian applicants is roughly 61 per cent, assessed on the applicant's own profile. STEM OPT is denied 8.7 per cent of the time, mostly on employer compliance. H-1B is denied only 2.15 per cent of the time but 24 per cent of petitions receive a Request for Evidence. Risk shifts from the applicant to the employer along the chain. ~61% refused F-1 visa Your profile — low OPT Timing 8.7% denied STEM OPT Employer's compliance 2.15% denied H-1B Employer's paperwork RISK YOU CONTROL RISK YOUR EMPLOYER CONTROLS H-1B denial is only 2.15% — but 24% of petitions draw an RFE
The refusal rate collapses along the chain, but the risk does not disappear — it moves from your own profile to your employer's paperwork. By H-1B, almost everything that goes wrong is a document someone else controls.

STEM OPT sits in a chain, and refusals cluster at the transitions: F-1 → OPT → STEM OPT → H-1B. Each handover has its own filing, its own deadline and its own failure modes.

If you are earlier in that chain, the F-1 refusal rules matter more, and the social media vetting rules introduced in 2025 now affect the visa stage directly.

Frequently asked questions

What percentage of STEM OPT applications are denied? USCIS denied 8.7% in FY2023, and roughly 15% of applications receive a Request for Evidence.

What is the most common reason for STEM OPT denial? Employer-side issues — chiefly E-Verify enrolment gaps exceeding 30 days before the OPT start date, and missing signatures on page 2 of the I-983.

Is there a grace period if my STEM OPT is denied? No. Denial takes effect without a grace period, which is why pre-filing checks matter more than remedies afterwards.

What is a CIP code mismatch? Your I-983 training plan must describe work related to your degree as classified by its CIP code. Duties that don't align with that classification are a common denial and RFE trigger.

When must I file? Within the 90 days before your current OPT expires. Filing outside that window fails on timing.

What changed in 2026? Wage-related RFEs are now issued when the I-983 is filed with a salary below the applicable prevailing wage determination.
