H-1B visa

The H-1B is a non-immigrant visa in the United States under the Immigration and Nationality Act, section 101(a)(15)(H). It allows U.S. employers to temporarily 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 to another non-immigrant status, find another employer (subject to application for adjustment of status and/or change of visa), or leave the U.S.

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.

The duration of stay is three years, extendable to six years. An exception to maximum length of stay applies in certain circumstances:

A time increment of less than three years has sometimes applied to citizens of specific countries. For example, during her time as an H-1B visa holder, Melania Trump was limited to one year increments, which was the maximum time allowed then per H-1B visa for citizens of Slovenia, which Melania Trump was then a citizen of.

H-1B holders who want to continue to work in the U.S. after six years, but who have not obtained permanent residency status, must remain outside of the U.S. for one year before reapplying for another H-1B visa if they do not qualify for one of the exceptions noted above allowing for extensions beyond six years. Despite a limit on length of stay, no requirement exists that the individual remain for any period in the job the visa was originally issued for. This is known as H-1B portability or transfer, provided the new employer sponsors another H-1B visa, which may or may not be subjected to the quota. Under current law, H-1B visa has no stipulated grace period in the event the employer-employee relationship ceases to exist.

The current law limits to 65,000 the number of foreign nationals who may be issued a visa or otherwise provided H-1B status each fiscal year (FY). Laws exempt up to 20,000 foreign nationals holding a master's or higher degree from U.S. universities from the cap on H-1B visas. In addition, excluded from the ceiling are all H-1B non-immigrants who work at (but not necessarily for) universities, non-profit research facilities associated with universities, and government research facilities. Universities can employ an unlimited number of foreign workers as cap-exempt. This also means that contractors working at but not directly employed by the institutions may be exempt from the cap as well. Free Trade Agreements carve out 1,400 H-1B1 visas for Chilean nationals and 5,400 H-1B1 visas for Singapore nationals. However, if these reserved visas are not used, then they are made available in the next fiscal year to applicants from other countries. Due to these unlimited exemptions and roll-overs, the number of H-1B visas issued each year is significantly more than the 65,000 cap, with 117,828 having been issued in FY2010, 129,552 in FY2011, and 135,991 in FY2012. In past years, the cap was not always reached. For example, in FY1996, the INS (now known as USCIS) announced on August 20, 1996 that a preliminary report indicated that the cap had been exceeded, and processing of H-1B applications was temporarily halted. However, when more accurate numbers became available on September 6, it became apparent the cap had not been reached after all, and processing resumed for the remainder of the fiscal year.
