Work Visas Explained: H-1B, L-1, O-1, and Other Employment-Based Options

H-1B: specialty occupation

The H-1B is for jobs that generally require a bachelor's degree or higher in a specific field, sponsored by a US employer. It's subject to an annual cap and lottery in most years, which makes timing important.

L-1: intracompany transfer

The L-1 allows a company to transfer an employee from a foreign office to a US office, generally for managers, executives, or employees with specialized knowledge. It doesn't go through the H-1B lottery.

O-1: extraordinary ability

The O-1 is for individuals with extraordinary ability or achievement in their field — often used by researchers, artists, athletes, and executives who can document a sustained record of recognition.

TN: for Canadian and Mexican professionals

Under USMCA, certain professionals from Canada and Mexico can work in the US in specific listed occupations, with a comparatively simpler process than the H-1B.

Employment-based green cards (EB categories)

Beyond temporary work visas, several employment-based green card categories (EB-1 through EB-3, among others) lead to permanent residence, generally requiring employer sponsorship and, for some categories, a labor certification process.

Which one fits?

The right category depends on your qualifications, whether you already have a US employer willing to sponsor you, and whether you're looking for temporary work authorization or a path to permanent residence.
