I stayed in US in L1 A for 6yrs and 10 mths and returned to my home country on May 2018. I had 52 days of staying outside US until that time. A petition was filed for the remaining 52 days that got approved. The petition was filed with exp. date of 12/08/2018.I did not go for stamping at that time as i was waiting for I 485 to be opened up for EB1. Unfortunately it never became current. Now, i completed by cool off period of 1 year by staying and working for the same company in my home country and i would like to use that petition and go for stamping. Can i use that and go for stamping and once arrived in US, will have our legal team apply an extension ?
