What is H1B Visa?

The H-1B visa is a non-immigrant visa that allows US employers to temporarily employ foreign workers in specialty occupations. These occupations typically require at least a bachelor's degree in a specific field.

Employers must file a Labor Condition Application (LCA) with the Department of Labor and obtain approval before petitioning USCIS for the H-1B visa. This data shows employers with approved LCAs.

Key points about H1B visas:

  • Valid for up to 3 years, extendable to 6 years
  • Requires employer sponsorship
  • Subject to annual cap (with exemptions for universities and research)
  • Allows dual intent (can apply for green card while on H1B)
