Hi, I have LLC in US. Also I have account in Bank of America. Now, I want to work in US. Can I go to work in US with EIN (Employer ID Number)? Or, I need a VISA and go to America with VISA and in US go to SSN? I am romanian. Thanks, Sergio.
If you want to work in America (rather than with an American company from your own country) you will have to get a visa. Here is some information about US work visas if you don't plan to immigrate permanently: http://travel.state.gov/visa/temp/types/types_1271.html
