Thanks for your reply whereismycase.
I understood your situation and think mine is a bit different from yours that we knew where the original labor was when we filed my 140 petition with a copy of the labor. It is in the file of the 140 petition of the original beneficiary, pending with the AAO's office for an adjudication. I believe the attorney has mentioned all these info for easy transfer of the original doc(may be the original beneficiary's 140 petition#, etc) along with the revoking of the original 140, when he filed our petition. Any thoughts or inputs on my case, if you had come across similar experiences in the group of missing original ETA-750s?
Your inputs are much appreciated.
