-The problem is that there is a deadline (normally 30 days) for you to respond to the RFE. If you get the RFE earlier than 30 days before the I-485 pending reaches 180 days, you can not 拖过180天. Of course, response to the RFE before I-485 pending > 180 days does not mean your I-485 will absolutely be denied.
我的理解是,在93天至180内换工作,工作相同,原雇主不撤销140, 没有任何风险? 对么?
-If your priority date is current and USCIS may decide to approve your I-485, then they find that it is still < 180 days since you change your job, and thus probably they will deny your I-485.
这种情况是用ead还是h1 transfer呢?
-Either, but you had better do H-1 transfer, especially you change job before I-485 pending > 180 days (there is risk).
