To qualify for the H1B Visa Program, a prospective employee must work in a 'specialty occupation'. Specialty Occupations currently include: medical/health care, computing and IT, teaching, finance and banking, engineering, legal and pr/marketing. H1B Visa jobs can be obtained with official sponsors located in the United States. Sponsors are generally large companies at the top of their chosen fields. The H1B sponsor employer files a H1B Visa Application of the behalf of the employee with the US Immigration Bureau. Individuals can not sponsor themselves, or apply for their own H1B visa. When awarded, the H1B Visa is only valid for work with the original employer. The employer will need to provide information about the applicant's job, including the duties, dates of employment and rate of compensation. If the applicant changes jobs, the new company will need to file a H1B Visa on their behalf.
