Hello Ron, I went thru all the articles under section AC-21 where you explained benefits of working on EAD after I-485 is pending for 180 days or more. Please advise on below question as I would be executing AC-21 in near future and I have this question in mind. I understand that, after 485 is pending for 180 days or more, even if employer revokes underlying I-140 petition, it should not have any impact. However I saw few unfortunate folks receiving RFE or even I-485 getting rejected without USCIS issuing RFE or NOID. In case I-485 is rejected in error by USCIS, would EAD be invalid immediately and alien would go out of status, loose the job etc. Can I-485 rejected be appealed in this case? Thanks for your time and help!
