I hope somebody will be able to give me an answer. My interview is next month. My I-140 was approved on 40 h/week job. I had to move and now I am working with another employer for 36 h/week (3 x 12 h night shifts/week). My case was transferred to local office. Will this be a problem for my interview? What should the verification letter from my new employer say? Just full-time, permanent job without specifying the hours is ok? Do I need a letter explaining that I am using AC21 to change employers? I am very nervous. Anybody with similar experience. Thanks
