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 New Hampshire

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

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 New Hampshire

New Hampshire's labor statutes do not impose a general E-Verify mandate; state law references E-Verify only as a way for an employer to establish an affirmative defense in a social-security-number misuse claim. Confirm with a lawyer whether any state contract or agency rule requires E-Verify for a particular employer. Separately, all employers must obtain documentation showing each employee's eligibility to work in the United States and maintain it for the period required by federal law. §RSA 275-A:4-a

Professional licensing

New Hampshire allows immigrants with valid work authorization to obtain professional licenses. The state has not enacted restrictive licensing legislation for those with valid federal work authorization.

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.
