I just got my visa transfered to a new company. The employer was very nice to me before but ever since I signed his contract and applied for mobility he has been acting rude and strange. My old soonsor gave me mobility after 6 months so I could work here for a better salary. It just got approved and transfered to my new sponsor but he's refusing to pay LMRA fees. He is saying that why should he and he didn't know about this before. I don't know what to do now. Is it possible to go back to my old employer or apply for a new job so soon.
