The first time I went to America for b2 visa, I-94 stayed at the customs.

1, maybe. You'd better buy a ticket to the city you plan to go to first. Transfer to America. 2. What are you doing? How long will you stay? Where are you going to play? Do you have any relatives or friends in America? Wait a minute. . . You can give it for six months. When you show your ticket to leave America, you will have 40 days. But the power of interpretation lies with the immigration officer. This means that the return date should be fixed. Print it out. 5. yes. English will be fine. 6. There are no 94 watches now.
