H1B Amendment in Premium Processing

Hi All,

My company processed my H1B for C1 Client and L1 Location. It got stamped without any issues. But that time I could not travel. Now I have another opportunity for C2 Client and L2 Location. For that my company filed my H1B amendment (location change) in premium mode but It got RFE. They are asking for Client letter and my Onsite Manager Letter. How long It could take to process by USCIS ? How much chance to get it approved ? Can someone please answer on this. Thanks in advance.

hi , i’m in the same situation and any update on your petition ?
