"THANKS for the reply Jaxen. I think I am not clear. I never worked for company "A" who is sponsoring my GC. All these days I am working for company "B". Company "A" has started my GC with an intention to take me in future. Now the company("A") is in trouble. Can my GC process be continued if I am stay with company "B" in the absence of company "A" supporting me further down the road? Can I make use of the EAD with company "B"(current employer) right away? " To me AC21 appears to speak only on the portability of employees ( those who are working c OR who had worked for the GC sponsorer only) but not clear about the employees who never worked for GC sponsorer. The straight answer I am searching for is: Can we use the portability clause by never working (past,present or future) for the GC sponsorer if we satisfy the 180 days clause?"
