Everything you need to know about transitioning from Optional Practical Training to H-1B status.
If you're an international student on F-1 status, transitioning from OPT to H-1B is one of the most critical steps in your U.S. career. The timeline is tight, the lottery adds uncertainty, and planning ahead is essential. This guide covers the key milestones, strategies, and fallback options for a successful transition.
The OPT to H-1B transition requires securing an employer sponsor by January-February for the March lottery registration, with H-1B employment starting October 1.
STEM OPT graduates get up to 3 lottery attempts. The cap-gap extension automatically covers your work authorization between OPT expiration and H-1B start date if your petition is filed.
| Company | H-1B Filings | Top Roles | Approval Rate |
|---|---|---|---|
| Amazon | 55,150 | Software Engineer, Data Engineer | 97% |
| 33,416 | Software Engineer, Research Scientist | 98% | |
| Microsoft | 34,626 | Software Engineer, Program Manager | 97% |
| Apple | 15,800 | Software Engineer, Hardware Engineer | 97% |
| Meta | 14,900 | Software Engineer, Research Scientist | 97% |
The OPT-to-H1B pipeline is the primary pathway for international students entering the U.S. workforce. Over 200,000 students use OPT annually, and STEM OPT extensions have become critical given H-1B lottery odds of roughly 25-30%. The lottery selection rate means most candidates need multiple attempts — making the 36-month STEM OPT window (3 lottery chances) essential for planning.
Employers increasingly understand this pipeline and many have structured new-grad hiring timelines around the March registration window. Starting your job search in your final semester — or even earlier — gives you the best chance of having an offer confirmed before registration opens.
Optional Practical Training (OPT) allows F-1 students to work in their field of study after graduation:
The STEM OPT extension is particularly valuable because it provides up to three chances to be selected in the H-1B lottery (filed in years 1, 2, and 3 of STEM OPT).
The annual H-1B registration window typically follows this schedule:
If your OPT expires between April 1 and September 30, and you have a pending or approved H-1B petition for October 1 start, you're automatically covered by the "cap-gap" extension. This extends your F-1 status and work authorization until your H-1B takes effect on October 1. The cap-gap only applies if your employer filed an H-1B petition (or your registration was selected and a petition was filed).
If you're not selected in the H-1B lottery, you have several options depending on your remaining OPT time:
Search thousands of verified H-1B sponsors by company, industry, and location.

Employers need to register you for the H-1B lottery by early March, which means you should have a job offer and confirmed sponsorship by January or February at the latest. Starting your search 6-8 months before the lottery window gives you the best chance.
In recent years, the H-1B lottery selection rate has been approximately 25-30%. In FY2025, USCIS received over 470,000 eligible registrations for 85,000 available slots. USCIS has implemented a beneficiary-centric selection process, meaning each individual can only be entered once regardless of how many employers register them.
If you're on OPT or STEM OPT, you can continue working for your employer while the H-1B petition is pending, provided your OPT is still valid or you're covered by the cap-gap extension. The cap-gap automatically extends your work authorization until October 1 if you have a timely filed H-1B petition.
If your H-1B registration was selected and your employer files the petition, the cap-gap extension automatically covers you from your OPT expiration through September 30. Your work authorization and F-1 status are extended. If you were not selected in the lottery, you must stop working when your OPT expires and consider alternative options.
