Big Four: Relocation for int'l students who don't get their H1b visa?

Hello guys,

I would like to ask, what actually happens to undergraduate international students with full time offers in auditing, at one of the big four, and they don't get selected in the H1b lottery? Will the Big four help you to relocate to another office outside of the US? I know that some tech companies and BB banks help their international hires to relocate to Europe such as London if they do not get their H1b visas.

I am curious about the case for Big four auditing hires because the Big four do have offices around the world but on the other hand auditing is less prestigious and it is not as transferable as consulting or banking from country to country.

I am an European Citizen in a similar situation, as described above, with a summer internship offer in auditing/assurance from PwC at the New York office. I want to make backup plans in case the Big four do not help you in any way if I dont get selected in the H1b lottery. And I really couldn't find any information online regarding this issue.
