My H1b transfer was initiated from A to B.
My I140 was approved 6 months back but I was not aware of it ( as USCIS showing as RFE received) and have receipt number with me.
My new employer B initiated H1B transfer with 140 receipt number and recently i got to know that my I 140 was approved 6months from employer A after we file H1B transfer to employer B.
What will happen in this case of H1B transfer?
It will process as normal. The I-140 has nothing to do with your H1B, it will not have any effect on the petition transfer.
