H1B Premium transfer received RFE

Currently working in Company A ,Transfer Visa to Company B on Premium process last week. Two days before we received RFE for client letter. I am going to work in X client through company B.Company B is saying after joining the Company only they can get client letter for MY RFE IS " Is it safe to join company B when Case Status is on RFE.Is there any chances of my H1B visa transfer will be  denied

Hi,

Since your transfer process is premium it is better to wait until you get the approval notice. Also you are not sure what is the RFE documents that the uscis is requested. Client letter can be given even before you join, if your really in need of that and also if they have option to give. Some companies never give client invitation letter…

Thanks
