Detailed Legal Guide & Practice Rules

Comprehensive breakdown of processes, requirements, and legal standards.

1. Common Nonimmigrant Work Visa Classifications

H-1B, L-1, O-1, TN, and E-3 categories

H-1B specialty occupation visas require at least a bachelor’s degree in a specific field and are subject to an annual congressional cap and electronic lottery, unless the employer is cap-exempt (such as universities and nonprofit research institutions).

L-1 intracompany transfers allow multinational corporations to transfer managers and executives (L-1A) or specialized knowledge staff (L-1B) from foreign offices. O-1 visas reward individuals with extraordinary ability in science, arts, education, business, or athletics. Canadian and Mexican professionals may qualify for streamlined TN status under USMCA.

2. Labor Condition Applications (LCA) and Wage Requirements

Prevailing wage levels, public inspection files, and employer compliance

Before filing an H-1B, H-1B1, or E-3 petition, the employer must submit a Labor Condition Application (LCA) to the U.S. Department of Labor certifying that they will pay the required prevailing wage and that hiring the foreign worker will not adversely affect domestic workers.

Common questions about work visas

Straightforward answers to the most frequent inquiries.

Can my spouse work in the U.S. while I am on a work visa?

It depends on your category. H-4 spouses of H-1B visa holders can only work if the H-1B holder has an approved Form I-140 immigrant petition. L-2 spouses of L-1 holders and E-2/E-3 spouses are employment authorized incident to status and may work without restriction.

What happens if my H-1B lottery registration is not selected?

Candidates not selected in the H-1B lottery may explore alternative pathways, such as cap-exempt employers (universities and research organizations), O-1 extraordinary ability visas, L-1 intracompany transfers after one year abroad, TN visas for Canadians/Mexicans, or pursuing advanced education with CPT/OPT eligibility.

This page explains how the work visas process generally works. It is general information, not legal advice, and it does not create an attorney-client relationship. Work Visas outcomes depend heavily on individual facts and on current policy, both of which change. Speak to a licensed immigration attorney about your own situation.
