O-1A — Extraordinary Ability - Sciences/Business/Education/Athletics

The O-1A is a US nonimmigrant visa for individuals with extraordinary ability in sciences, business, education, or athletics. No annual cap applies and no specific degree is required — applicants must show sustained national or international acclaim by meeting at least 3 of 8 evidentiary criteria.

Initial stay is up to 3 years, with extensions in 1-year increments and no maximum total duration. Dual intent is permitted, making it a common precursor to EB-1 permanent residence. Spouses and unmarried children under 21 qualify for O-3 status but may not work.

This visa is ideal for top scientists, executives, academics, or athletes who can document sustained international acclaim and have a US employer or agent to file on their behalf.
