回复：Offer letter can be cancelled

Thank you. But I doubt it. well I maybe wrong. Because for those people who get a job offer from US company and apply for H1B visa to enter the US, just like first time F1 visa, it is impossible to have pay tub unless people get visa to go to US to work. it is just like it is impossible for international students to show registration of 12 credits unless you enter the US first to study under F1 visa.(They can show letter of admission, which is like offer letter).

Any opinions or info. are welcomed.
