Hi Ron, I received my GC through my current employer as eb2. We have used PD porting from my previous employer approved 140. After getting my GC, previous employer requested to withdraw approved I140 since I don't work for him now. USCIS denied request saying, that 140 has been used by beneficiary and got his GC. Can this cause any issues in future? I read on another forum, where there was a case uscis wanted to revoke 140 which was used to port PD and as per them it might cancel GC as well. Appreciate your help! ====== A year and a half after obtaining permanent residence, Mr. Worker learned that USCIS had issued a Notice of Intent to Revoke ABC, Inc.’s approved I-140 and the company was given 30 days to respond. The Notice was quite vague regarding what lead the Service to believe revocation was necessary and did not take into consideration the fact that the company had already requested withdrawal of the approved I-140. It simply stated that ABC, Inc. had filed a high number of petitions and must establish that its permanent job offer from 2006 was a realistic one. ABC, Inc. was asked to submit a list of all I-140 and I-129 petitions it had filed, demonstrate that the company had the ability to pay the salary offered, submit evidence that it was still in business, and provide documentation to substantiate its address. There was no indication of what caused the Service to question whether the business still existed, only a generic statement that the company had filed an unusually high amount of petitions.
