Hiring plans need dates. The O-1's dates are unusually plannable, because nothing waits for a government season.
No March registration, no lottery odds, no April-to-October dead air. This year's H-1B cap closed on July 17, 2026; the next registration window is approximately March 2027. None of those dates constrain an O-1 hire.
Year-round filing, 15-day premium processing decisions, and no lottery window: the O-1 timeline an employer can plan around.
