what I have to do without job and client letter ?

My application has been picked up in lottery for premium processing from california. I am waiting for result.But I have lost a job. When I applied for H1B without client letter,bt I have provided just client name and location. So, what I have to do if in case I get a RFE??Waiting for positive response!!!

You lost the job w/ the employer who filed your H-1? In that case, the employer may no longer be ready to support your petition. They may either withdraw it or not respond to any RFE.
