No, he is wrong. You couldn't cross the border, if you don't have the visa, no matter by driving your own car, or by grey hound. Trust me. Go apply for the visa!
Do I need a visa?I will have business trip to States in June. I may go there by car. Do I need to apply for a visa right now? My boss said I dont need a visa cause I am an immigrant. Any help is greatly appreciated.
