How to Complete I-9 Verification with Cap Gap

May 27, 2026

Certain F-1 students may qualify for an automatic “cap-gap” extension if their employer timely files an H-1B petition requesting a change of status with an October 1 start date. The cap-gap extension allows eligible students to remain in the United States and continue working during the period between the expiration of their F-1 status or OPT employment authorization and the beginning of their H-1B status on October 1.

In May 2025, USCIS updated its I-9 Handbook to reflect the extended H-1B cap-gap protections now available to eligible F-1 students. The revised guidance is especially important for employers managing reverification obligations during the transition from F-1 OPT employment to H-1B status.

What Is the H-1B Cap-Gap Extension?

The H-1B “cap-gap” refers to the period between the expiration of an F-1 student’s OPT or STEM OPT employment authorization and the start of H-1B employment authorization.

Eligible F-1 students who are beneficiaries of timely filed H-1B cap-subject petitions requesting a change of status may receive an automatic extension of:

• F-1 status; and
• Employment authorization.

Historically, cap-gap protections extended only until October 1, when the new fiscal year H-1B period began. However, recent regulatory changes extended certain cap-gap protections beyond October 1 in limited circumstances, prompting USCIS to revise the M-274 Handbook for Employers and update Form I-9 guidance accordingly.

Why the USCIS I-9 Handbook Update Matters

The May 2026 updated USCIS guidance clarifies how employers should complete and reverify Form I-9 for employees working pursuant to the cap-gap extension. Incorrect I-9 completion can expose employers to penalties during an ICE audit or government inspection, making accurate compliance procedures essential.

Acceptable Documents for I-9 Verification During Cap-Gap

Under the updated guidance, eligible F-1 students may present:

• An expired EAD; and
• Form I-797C, Notice of Action, confirming that an H-1B petition was filed before the EAD’s expiration and requesting change of status.

These documents together establish continued employment authorization during the cap-gap extension period.

In prior years, employers frequently relied on a Form I-20 endorsed by the Designated School Official (DSO) recommending the cap-gap extension. While the endorsed Form I-20 may still serve as supporting evidence in practice — particularly where USCIS receipt notices are delayed — the updated USCIS guidance emphasizes the expired EAD and Form I-797C combination.

How Employers Should Complete Form I-9 Reverification

When reverifying an employee under cap-gap authorization, employers should:

• Review the employee’s expired EAD;
• Record the Form I-797C receipt information;
• Enter “Cap-Gap” in the Additional Information field;
• Retain copies of the supporting documentation with the Form I-9; and
• Track future reverification deadlines carefully.

Employers should also monitor the status of the H-1B petition. If the petition is rejected, denied, revoked, or withdrawn, cap-gap work authorization may terminate immediately.

Extended Cap-Gap Rules Create New Compliance Considerations

The 2025 USCIS update reflects broader changes intended to reduce disruptions for international students and sponsoring employers. However, these expanded protections also create new compliance responsibilities.

HR departments should ensure that:

• Internal I-9 procedures are updated;
• Hiring managers understand cap-gap documentation rules;
• Reverification calendars are monitored carefully; and
• Immigration counsel is consulted when unusual documentation issues arise.

Given ongoing USCIS processing delays and evolving immigration regulations, proactive compliance planning is more important than ever.

Conclusion

USCIS’s updated I-9 guidance provides important clarification for employers managing F-1 students transitioning to H-1B status under the cap-gap extension rules.

While the revised rules offer greater continuity for employers and foreign national employees, they also reinforce the importance of accurate Form I-9 completion and timely reverification practices.

Businesses employing F-1 students should review their current I-9 procedures and ensure HR personnel are prepared to handle cap-gap cases correctly during the 2027 H-1B season and beyond.
