I guess, when INS send the approval letter after local office interview, they would have sent the order for the card it seems. Because, in the approval it says, you will be receiving your card in 6-8 months. etc.
Also, when I went for stamping after receiving the approval letter, i didn't fill up any form (because i did finger print and sign on I-89 on the interview day); Also I-94s were taken by the officer during the interview.
When I went for stamping today, they just stamp it on my passport at the entrance itself. That means, i don't have to go and wait etc.
I hope they already ordered for card. Since i doubt that, online status may not get updated for local transfer cases.
