My employer is a manufaturing company, they sponsered my GC. I have been working with them for last 4 years. My 485 (PD 2004 -EB2-India) is pending for more than 1 year. 140 is already approved. I already used AC21 for employment relocation, with same GC sponsering employer (state to state transfer). We informed USCIS about my emplyment relocation. This happened 4 months ago. Now my employer about to lay off me (may be today), due to their finiancial constrains. However, they may support me in GC, in terms of documents. I am not a IT guy, it takes some time (may be 1 to 3 months) for me find same or similar job. In this situation what kind of support I should ask from my employer? Can I get a letter saying that "I will be hired after I get permanant residence, till then I will be in leave of absense"? Can this letter help me to maintain my status..Help me please.. Thanks...
