I was approved on Dec 13th according to an IO i spoke with. I had called the 800 number to enquire about the status of my RTD application that I sent in 3 months ago, since I was planning to travel to Europe this Saturday, the rep connected me with an IO who wasn't helpful at all. So i just asked her about the status of my I-485 and she said it was approved, I was shocked to hear that.My initial disappointment for not getting my RTD in time to travel turned in to joy. I gave her my LIN again to reconfirm since I have not seen any updates on my case since April and she confirmed it. I called them again yesterday to verify whether it was so, and indeed it was,the SOBs at USCIS have finally approved my case. As of today,I still have not received any information written or via email.
