The H1B visa is commonly known as work visa to USA. H1 visa is an employment based visa that can be granted for an eligible and qualified temporary worker. For such a visa, an employer must offer a job and apply for your H1B visa petition with the US Immigration Department. This approved petition (approved form I797) is a work permit which allows you to obtain a visa stamp and work in the U.S. for that employer. An H4 visa is issued to dependent family members (spouse and children) of H1 visa holders who would like to accompany the H1B visa holder in the U.S. during their period of stay. This article outlines the complete process for H4 dependent visas for H1B visa holders. In such a case, the principal applicant is always the H1B visa holder. Immediate family members like spouse and children under 21 years old may qualify for an H4 visa and may apply at a US Consulate in their home country.
H1B visa is issued for a specialty occupation, requires theoretical and practical application of a body of specialized knowledge and requires the visa holder to have at least a Bachelor’s degree or its equivalent.
Once you have an approved H1B petition, you can setup a H1 visa interview with nearest applicable US consulate or embassy
