劳工有两份approved I-140s. One is based on EB2 LC, with a PD of Nov 2004 and I-485 filed for less than a month. The other one is based on EB2 NIW with a PD of Jan 2006, so certainly no 485 is filed based on it. LC based I-140 was petitioned by the company and NIW was by us.
现在劳工上班的公司（就是filed 了劳工卡的那家），情况不太好，很有可能等不到１８０天就会关门，AC 21自然是靠不上了。但是他们也不会去取消劳工卡的１４０。如果这种情况发生，我们可以把现在的４８５挂靠或新file一份４８５到NIW I-140上，claiming the PD of LC based I-140 which is current (Nov 2004),因为两份１４０都批准了?
或者运气好一点，过了１８０天关门，用AC 21换工作的话，要马上即时通知移民局老公用了AC 21,还是等RFE?
我上次问了小白兔好几个问题，都得到及时答复。非常感谢！
