I have my I140 approved last year in June 2015 with priority date at June 2014 from company A and I have an offer from a company B, which I am planning to accept. . My new employer told me that they will file my perm application . I had few questions :
If somehow my new employer does not file my perm application and I change my job again to employer C Will employer C be able to apply my perm application and will I be able to retain my priority date ?
Is there any time period in whch perm application has to be applied once last perm application was approved ?
Is there a possibility that I will not be able to retain my priority date?
Any other worst possibility that can happen ?
