Hi Ron, I have an approved H1B petition till Sept 2017. I work on Employer Vendor Client model. My H1B petition was filed for a client (X) in Florida. Then last September I moved over to California for a new client (Y). No LCA or amendment was filed by my employer for Client Y. Now in June 2015, I have moved to a new client (Z). Now my employer wants to file for the new LCA and do H1B amendment for client Z. So my questions are: 1. Can my employer file for LCA and H1B amendment for client Z now (after I have already joined client Z. It's been a month now with client Z)? 2. Will USCIS any way come to know that my employer did not file for LCA and H1B amendment for Client Y? 3. Also my wife's H1 (from H4) in process. Will my H1 amendment affect my wife's H1 process at all? Do we need to file for H4 amendment as well? Thank you in advance for your response.
