H1-B transfer

[kvarun]

I have just resigned company A and joined company B which is an desi consultancy. After joining we figured out that there were 3 vendors between my employer and client. So the relation is Employer- mid vendor-mid vendor-Prime vendor-Client. We got an RFE today asking us to explain the relationship.
Even if client provides client letter or not what is the possibility of approval?
If all the docs between layers were provided, is there any chance for approval?
Is there any rule that there should not be more than 2 layers between Employer and Client?

Thanks

If the documents establish your relationship with your employer (the consulting company) with you as an employee, the petition will be approved. It depends on the nature of agreements between all those layers. There is a likelihood in this case that the petition will not be approved. But the only way to know is to submit what you can and wait. You can also consult an experienced immigration attorney who can suggest better documentation.

Thanks kabkaba. Even my employer is not so confident about the approval. I left my previous employer on May 31. He haven't revoked petition yet.
So, in this case can I join my previous employer?

Yes

Do I need to leave and re entrer US?
