The H-1B1 visa is a variant of the H-1B visa specifically designed for professionals from Chile and Singapore. It allows them to live and work in the U.S. in a specialty occupation. The occupations for an H-1B1 are similar to those of the H-1B, requiring a body of highly specialized knowledge and at least a bachelor's degree or its equivalent.
The H-1B1 Visa allows an initial stay of up to one year. Extensions can be granted, but unlike the H-1B visa, there is no six-year maximum limit. Spouses and children of H-1B1 visa holders may enter and remain in the U.S. in H-4 status. However, H-4 dependents are not permitted to work in the U.S. unless they have their own work visa.
As with the H-1B Visa, an employer must submit a petition for an H-1B1 Visa, which includes information about the job and the qualifications of the prospective employee. One key difference is that the H-1B1 category has a separate cap, with 1,400 visas available for Chilean nationals and 5,400 set aside for Singaporean nationals each year.
