What is the H-1B visa lottery?

The H-1B has an annual cap of 65,000 visas (plus 20,000 for U.S. master's degree holders). When applications exceed the cap, USCIS conducts a random lottery. Employers must register during the designated period (typically March) [§ 8 U.S.C. 1184].

Can I change employers on a work visa?

H-1B portability allows you to begin working for a new employer as soon as the new petition is filed (not yet approved). Other visa types have varying transfer rules. Always consult an attorney before changing jobs.

Work Visas & Employment-Based Immigration in Texas

H-1B, L-1, O-1, PERM labor certification, E-Verify requirements, and professional licensing in Texas.

Employment-based immigration allows foreign nationals to work in the U.S. temporarily or permanently. The INA establishes several visa categories and employer sponsorship requirements §8 U.S.C. 1153.

Common work visa categories

	Duration	Key requirement
H-1B	3 years (renewable to 6) §8 U.S.C. 1101	Specialty occupation requiring bachelor's degree or higher
L-1	1-3 years (renewable) §8 U.S.C. 1101	Intracompany transferee in managerial or specialized knowledge role
O-1	3 years (renewable) §8 U.S.C. 1101	Extraordinary ability in sciences, arts, education, business, or athletics
TN	3 years (renewable) §8 U.S.C. 1101	USMCA (formerly NAFTA) professional from Canada or Mexico
E-2	2 years (renewable) §8 U.S.C. 1101	Treaty investor from qualifying country

E-Verify in Texas

Required for state agencies under Texas law; confirm the current scope of the requirement with a lawyer. Not mandatory for all private employers. Multiple legislative efforts to expand mandatory E-Verify to all employers have been introduced but not enacted as of 2025.

Professional licensing

Texas law addresses how state licensing agencies treat an applicant's immigration status, and some work-authorized immigrants, including DACA recipients, may be able to obtain certain professional licenses. However, certain licenses may require U.S. citizenship or lawful permanent resident status depending on the licensing board.

PERM labor certification

For permanent employment-based green cards, most employers must complete the PERM labor certification process through the Department of Labor, demonstrating that no qualified U.S. worker is available for the position §8 U.S.C. 1182(a)(5).

✓Work visa petitions are time-sensitive. H-1B petitions are subject to an annual lottery. Start planning well in advance of any employment start date or status expiration.
