h1b transfer 1 month after coming to US

[dream!]

I came to US and started working on 10th July for company A and unfortunately the contract has been shortened to 2 months. I started trying for contract to hire opportunities and got a project with a reputed client. A consultancy company B is ready to do my h1 transfer and take me as a W2 contractor. As I have been working with company A only for 1 month, I dont have the paystubs for the duration till now because of the delay in joining formalities (Applying for SSN and getting the SSN number, creating a bank account and getting cheque book which is required to complete the joining formalities) only after which I will be entered in the payroll. 

 

As company B is going to start the H1 transfer process, will the absence of paystubs be a showstopper? 

Will it be risky to resign from company A now?

First of all the rule of thumb is do not join another employer till your H1B petition is approved. Avoid multiple layers in work. Joining a consultancy is always risky as you might end up getting RFE and chances of denial are high. Look for a direct employer.
