H2B VISA:
The H2B visa is a non-immigrant visa available to workers in non-agricultural fields when U.S. employers have seasonal, peak load, or intermittent needs for temporary workers. It can also be obtained when a U.S. employer has a one-time occurrence that requires additional temporary workers. Employers must also be able to prove that there is an insufficient supply of available American workers to perform these jobs, thus necessitating bringing in foreign workers.
H2B Visa Qualifications
In order to qualify for the H2B visa, applicants must have a job offer from a U.S. employer for temporary or seasonal work and must be able to show the intent to return to their home country when the visa expires. The H2B visa is not self-petitioned, meaning it must be sponsored by an employer.
Dependants (spouse and unmarried children under age 21) can be brought to the United States with the H2B visa holder under H4 status, but they are not allowed to work in the United States during that time. As many as 66,000 H2B visas can be granted per fiscal year.
