Visa to the United States H 1l 1b 1 What's the difference between these three visas?

H 1 is the work permit issued by the United States to senior scientific and technological personnel, L 1 is the work permit issued by the United States to managers of multinational enterprises, and B 1 visa is issued to applicants engaged in short-term business activities in the United States.

2. Different requirements

L visa applicants must hold management positions or have professional knowledge in the United States, and have worked for the same employer or company for at least one year in the three years before applying for a visa. L 1 and H 1 are not required.

3. Different functions

L 1 Visa holders can work legally in the United States. B 1 Visa holders are not allowed to work in the United States. Because the B 1 visa is a short-term visa issued for business-related activities, you can't engage in any employment. L 1 visa managers can work in the United States for up to seven years, and H 1 visa beneficiaries can work in the United States for six years.
