h-1

The H-1B is a visa in the United States under the Immigration and Nationality Act, section 101(a)(15)(H) which allows U.S. employers to employ foreign workers in specialty occupations. If a foreign worker in H-1B status quits or is dismissed from the sponsoring employer, the worker must either apply for and be granted a change of status, find another employer (subject to application for adjustment of status and/or change of visa), or leave the United States. Effective January 17, 2017, USCIS modified the rules to allow a grace period of up to 60 days but in practice as long as a green card application is pending they are allowed to stay. In 2015, there were 348,669 applicants for the H-1B filed of which 275,317 were approved.
The regulations define a "specialty occupation" as requiring theoretical and practical application of a body of highly specialized knowledge in a field of human endeavor including but not limited to biotechnology, chemistry, architecture, engineering, mathematics, physical sciences, social sciences, medicine and health, education, law, accounting, business specialties, theology, and the arts, and requiring the attainment of a bachelor's degree or its equivalent as a minimum (with the exception of fashion models, who must be "of distinguished merit and ability"). Likewise, the foreign worker must possess at least a bachelor's degree or its equivalent and state licensure, if required to practice in that field. H-1B work-authorization is strictly limited to employment by the sponsoring employer.
On March 3, 2017 the U.S. Citizenship and Immigration Service announced on their website that starting from April 3, 2017 they would temporarily suspend premium processing for all H-1B visa petitions until further notice. On October 3, 2017 premium processing for all H-1B visa petitions was resumed. On April 18, 2017 President Trump signed a "Buy American, Hire American" Executive Order which sets broad policy intentions directing federal agencies to propose reforms to the H-1B visa system that currently allows extended stay for temporary skilled workers which allows transition into citizenship without any purview of federal discernment and regulations or quotas that balances growing job needs of American population. However, Trump administration revealed they are not considering any proposal that would force H-1B visa holders to leave the country and will gradually focus on increasing the quality of life of the current visa holders.
