Guides
Work Visas
H-1B, L-1, O-1, TN, and E-2 guides for employers and workers.
A work visa lets a foreign professional hold a specific job for a specific employer for a limited time. Each category has its own logic — the H-1B lottery and its specialty-occupation test, the L-1 for transfers inside a company, the O-1 for people at the top of their field, the TN for Canadian and Mexican professionals, and the E-2 for investors from treaty countries.
The guides here explain who qualifies for each, how the petition is built, what the government fees and timelines look like, how transfers and extensions work, and what changes when the employee wants a green card. They are written for both sides of the petition: the employer who files and the professional whose career depends on it.
When it is time to file, the work visa service pages describe Atlas Immigration Law's flat-fee handling of each category, from strategy through approval and the extension that follows.
