H 1B visa is the most important work visa in the United States. It is a non-immigrant visa issued to employees with foreign nationality and professional skills employed by American companies. H 1B visa holders can work in the United States for three years, which can be extended for another three years. After the expiration of six years, visa holders must leave the United States if their status has not changed.

quota administration
You don't need to provide TOEFL and IELTS scores to apply for an American HIB visa, but there are places every year. According to the current law, the annual quota of foreigners before the fiscal year 2003 was 65,438+095,000. After "9 1 1", the annual visa quota was reduced to 65,000 in order to prevent terrorists from entering the country.
Among the 65,000 quotas in fiscal year 2007, except for 7,000 quotas in Chile and Singapore, other countries can only apply for 58,000 quotas. Therefore, the annual quota application for H 1B is very tight. Only in April and May, Indians occupy most of the quotas because of their language and technical advantages.
Applying for an H 1B visa requires a guarantee from an American employer. Employers must file an application form for labor status (LCA) with the US Department of Labor, and guarantee to pay salaries and provide working conditions according to prevailing salary standards. At the same time, the employer should also submit the I- 129 form to the US Immigration Service (BCIS) and pay the corresponding attorney fees and application fees.
