The H1B Visa is a non-immigrant visa that allows U.S. companies to employ foreign workers in specialty occupations. These jobs typically require a higher education degree or its equivalent in experience. The visa is valid for three years and can be extended for up to six years, making it a popular choice for skilled professionals. To obtain an H1B Visa, employers must file a petition with the U.S. Citizenship and Immigration Services (USCIS) and demonstrate that the position requires specialized knowledge. The process includes a lottery system due to high demand, with a limited number of visas available each year.
