What does the corporate immigration process look like for businesses hiring foreign workers?

This is generally about sponsoring the foreign national on a work visa such as an H-1B or if they are being transferred from the company’s office abroad, an L-1 Intracompany Transferee visa. There are also a handful of special work visas that have benefits over the H-1B for countries that have special treaties with the United States such as the E-3 for Australians, TN for Mexicans and Canadians, and the H-1B1 for Singaporeans and Chileans. In addition, around 80 countries have access to the special E-1 and E-2 Treaty Trader/Investor visas.
