F-1 to H-1B Gap: Surviving Between OPT End and H-1B Start Date
OPT expires before October 1st H-1B start date? Here's how to bridge the gap legally without leaving the country.
Quick Answer
OPT ending before October 1st H-1B start creates status gap. Solutions include Cap-Gap extension (automatic if H-1B selected by April 1), remaining in U.S. without work authorization in lawful pending status, employer starting you October 1st rather than sooner, changing to B-2 visitor status for gap period, or leaving and returning October 1st with new H-1B visa stamp.
Key Takeaways
Cap-Gap extension automatically extends F-1 status and EAD until Oct 1 if H-1B selected
You can stay in U.S. without working during gap if H-1B petition pending
Employer must agree to October 1 start date, not earlier
B-2 visitor status is possible but prohibits all work
Leaving and returning with H-1B visa stamp is safest but inconvenient
STEM OPT extension provides 24-month additional buffer eliminating most gaps

Understanding the Gap Problem
H-1B visas always start October 1st regardless of when approved. If your OPT expires in June, July, August, or September, you face gap between OPT end and H-1B start. During this gap, you have no work authorization and potentially no legal status unless you use one of several bridging strategies.
Many international students face this problem. Standard OPT is 12 months from degree completion. If you graduate in May, OPT runs through the following May. If selected in H-1B lottery (results announced late March/April), your H-1B starts October 1st, creating a 5-month gap between May OPT end and October H-1B start.
Common gap scenarios:
Graduate May 2024, OPT expires May 2025, H-1B starts October 2025 (5-month gap)
STEM OPT expires September 2025, H-1B starts October 2025 (1-month gap)
Regular OPT expires July 2025, H-1B starts October 2025 (3-month gap)
Cap-Gap Extension (Automatic Solution)
Cap-Gap extension is automatic status and work authorization extension for F-1 students whose OPT is expiring and who have been selected in H-1B lottery. If your OPT expires between April 1 and September 30, and you were selected in H-1B lottery, your F-1 status and work authorization automatically extend until October 1st.
This requires no separate application. Once your employer receives H-1B selection notice and files the petition, your status extends automatically. You receive updated I-20 from your school's international student office showing the Cap-Gap extension.
Cap-Gap eligibility requirements:
Currently on valid F-1 OPT (regular or STEM)
OPT expires between April 1 and September 30
Employer files H-1B petition for you as new hire
H-1B petition selected in lottery
Petition filed before OPT expires
If these conditions are met, you continue working legally from OPT expiration through September 30. On October 1, you start on H-1B status.
Remaining in Pending Status
If Cap-Gap doesn't apply (OPT expired before April 1st but H-1B petition is pending), you can remain in U.S. in lawful pending status but cannot work. This is uncomfortable limbo but legal.
Once OPT expires, you must stop working immediately. You can stay in U.S. while H-1B petition is pending approval, but you cannot be employed in any capacity. Live on savings or family support during this period. When H-1B is approved, you can begin working October 1st.
Requirements for pending status:
H-1B petition filed before OPT expired
Petition is pending approval (not yet approved or denied)
You maintained legal F-1 status continuously
No employment during gap period
This creates financial hardship but keeps you in U.S. legally. Employer must agree to October 1st start date and understand you cannot work during summer.
B-2 Tourist Status Change
Some students change to B-2 tourist status to bridge the gap. File I-539 change of status to B-2 before OPT expires. If approved, you can legally stay in U.S. as tourist through September, then start H-1B October 1st.
The challenge is B-2 prohibits all employment and is intended for tourism. USCIS may deny applications clearly using B-2 only to bridge employment gap. Additionally, USCIS processing times for I-539 are often 6-12 months, meaning you might not get decision until after H-1B already started.
This option is risky and generally not recommended unless you have legitimate tourist purpose during gap period.
October 1st Start Date Coordination
Simplest solution is ensuring employer agrees to October 1st start date with no work before that. Many employers want you starting as soon as OPT begins or immediately after graduation, but H-1B law doesn't allow this for cap-subject petitions.
Negotiate October 1st start during job offer process. Explain you can begin on OPT initially but if selected for H-1B, you'll need October 1st transition. Clear communication prevents problems later.
STEM OPT Extension (24 Months Total)
STEM degree graduates qualify for 24-month STEM OPT extension on top of standard 12-month OPT. This is the best long-term solution to gap problem. With 36 months total OPT (12 regular + 24 STEM), you have three H-1B lottery chances and minimal gap risk.
STEM OPT timeline example:
Graduate May 2023
Regular OPT: May 2023 - May 2024 (first lottery chance)
STEM extension: May 2024 - May 2026 (second and third lottery chances)
If selected in 2024 lottery, H-1B starts October 2024 before May 2026 expiration (no gap)
File STEM OPT extension before regular OPT expires. Processing takes 2-4 months, but 180-day automatic extension prevents employment gaps while petition is pending.
Gap Timeline Comparison
Situation | Gap Period | Can Work? | Can Stay in U.S.? | Best Solution |
|---|---|---|---|---|
OPT expires May-Sept + H-1B selected | May-Sept | Yes with Cap-Gap | Yes | Cap-Gap extension (automatic) |
OPT expires before April + H-1B pending | Until Oct 1 | No | Yes | Remain in pending status, don't work |
OPT expires + H-1B approved | Until Oct 1 | No | Yes | Wait for Oct 1 start |
On STEM OPT | Usually none | Yes until STEM expires | Yes | 24-month STEM extension covers gaps |

Frequently Asked Questions
Will I automatically get Cap-Gap extension?
Yes, if your OPT expires April 1-September 30 and your H-1B petition was selected and filed timely. School's international office provides updated I-20 confirming extension.
Can I travel during Cap-Gap period?
Risky. Cap-Gap extension only maintains status within U.S. If you leave and try to return before October 1st, you may be denied entry. Best to stay in U.S. during Cap-Gap.
What if OPT expires in March?
Cap-Gap doesn't apply. You can remain in U.S. without working while H-1B petition is pending, or leave and return October 1st with H-1B visa stamp.
Do I need new visa stamp for H-1B?
Not immediately. Change of status to H-1B happens within U.S. October 1st. You only need H-1B visa stamp stamped in passport if you leave U.S. and want to return.
Can I start side hustle during gap?
No. Any employment violates status whether full-time job or side hustle. If on pending status or B-2, you cannot work at all in any capacity.
