进入美国的保证一般只有公民。其次是绿卡，但也有绿卡当场没收的少数情况。
此外就要看个别状况了。但不至于永远来不了美国。而要看以什么理由来美国。
如果你现在签证是H1B，你把专业的证件也带着，工作地址带着。一般不会有问题。
Passport with valid H1B Visa stamping on it.
If you have any professional licenses or certificates, you can carry
them as well. You will need the address information of where you will
stay in America. You will have to fill it out in the I-94 form that you
submit at the port of entry.
