Hi All,

My H1 B process was intitated while I was working for Project A, now, my project is ending soon. I am yet get into a new project.

USCIS has requested RFE, asking for client invitation letter. I have previously submitted ProjectA’s client invitation letter. My project would end by this July’2014.
