3/17/2010 my Eb1a 485 was approved. then the lawyer decided to relink my kid's already filed 485(Eb2) based on her mom to my Eb1a instead of filing the 2nd 485.
I did not call USCIS at all. But my lawyer directly sent the relinking request to the senator for help in 3/25/2010.
To my surprise, tonight got the text message and got from online that my kid's 485 was relinked successfully and the card was ordered!!!!
haa i thought to call USCIS next week. so quick and luck!!!
good luck to you all
