非常感谢8老师的回答，还有一问题..

如果I-485 pending后过了180天，由于失去工作,但找到的新工作(similar field)工资低于prevailing wage,(new employer not support GC application, didn't use prevailing wage?). 这会不会在批485时出问题 in RFE？

thank you

如果I-485 pending以后过了180天，这时候失去工作会不会在批485时有问题？
-Sooner or later, USCIS will send you RFE for your employment status. If you don't have a job or job offer in the same /similar field (not need to have the same job/responsibility, but need to be in the same field) when you get the RFE, your I-485 probably will be denied.

或者这时如果找到的新工作与以前的性质不同行吗？-No.
 

thank you
