There are hundreds of different visas available that foreigners can apply for to live and work in the United States. The bottom line, however, is that there are very few visas that people actually qualify for. In the world of US Business Immigration, the 4 main visas that apply to executives, business owners, managers and entrepreneurs are the E2 Investor Visa, E1 Treaty Trader Visa, L1 Intracompany Transferee Visa and the EB5 $500,000 or $1 million visa/green card.
