This morning, my wife and I went to the the local office to inquire whether our NCs are clear or not. After logging on his computer, the officer told us that our I-485 were approved this Monday (June25) and we will receive the notice and card within 10 days. But when we came home and logge on our computer, we found that there are no updating on our I-485. In the meanwhile, several friends in this forum received their approval notice by email (the system) that they were approved this Tuesday (June 26). I don't know hoe to explain this phenonmenon. When I get our confirmation notice, I will share my story with the friend in this forum.
