How the H-1B cap works
65,000 plus 20,000, a registration in spring, and an October 1 start.
The facts
- Congress set the regular H-1B cap at 65,000 per fiscal year, with an additional 20,000 for beneficiaries who hold a master's degree or higher from a U.S. institution.
- Employers register each beneficiary electronically during a registration period USCIS announces every year; in recent years it has opened in March. If registrations exceed the cap, USCIS runs a selection — weighted by the offered wage level from the fiscal year 2027 season — and invites the selected employers to file petitions.
- Cap-subject H-1B employment can begin no earlier than October 1, the first day of the federal fiscal year.
- Some employers are exempt from the cap, including institutions of higher education and certain nonprofit or government research organizations. Petitions to extend or amend existing H-1B employment are not counted against it.
- ImmigrationClock tracks the registration window and the October 1 start on its key dates page, and links USCIS's own cap-season page for the current year's instructions.
Why it matters
The cap is the reason "H-1B season" exists. A reader who knows which petitions are capped, and when the window opens, can tell a real deadline from a headline.
