I filed for my H1b in 2012 and it was approved . At that time I was working for New York City - Taxi Limousine Commission and in January I started working for New York City - Landmarks Preservation Commission . I am planning to go for H1b interview and I will get the client letter from New York City - Landmarks Preservation Commission . . So in my case am I supposed to get my H1b amended or just need to update the LCA with the new client location ?
