H1B RFE for contract documents

[imcheck]

I got RFE. I am able to find new job two weeks back. I am planning to join in next week. USCIS asking for all contract documents. I can present old contract documents. I am confused on new contract details. I have been recruited by big company(B) and they provide services to various clients. My repporting manager sits at B (different city) but I should work at client (C) place(onsite). It seems like project is outsourced to company B. I don't think I can get contract details between B and C. Who is my client now? Is it company B or company C? I have to provide location of work. I don't have much time please advice me what to do. My I94 expires on july 30th. I need to respond RFE quickly. Really appreciate your help.

My spouse is on H1B. Worst case I would like to go for H4 or I will transfer my H1b to different company. If I do transfer I might face same issue with contract documents. Please advice...

Thanks in advance

You have said you should work at client C, so you already have answer to ur question 'who is my client now?'.

Submit whatever documents you have.

well..I don't think I can get contract between B and C. Because it would be at highlevel not associated with any individual. It is outsourced project to B and It is going to control all my duties. For example B is IBM.

What should I do if H1B extension gets rejected. Should I file H1B transfer immediately? Apply for MTR? Do both at same time? Apply for H4 ? Should I apply for H1 Transfer before I94 expires while RFE is in pending? I have approved I140, How can I use this for H1B transfer? I still have one and half year left to finish 6 years. Please advice me. I do not have much time..

Thanks in advance.
