2003 eb3 接到的email, ，請幫忙

On April 28, 2009, we transferred this case to our NATIONAL BENEFITS CENTER location to conduct the interview that is a standard part of processing this I485 APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS. You will be sent a notice when the interview is scheduled, or if the office needs something from you

有誰有類似經驗的嗎？是要interview我嗎？我應該準備什麽東西嗎？本以為eb3今年名額用完了就沒什麽事兒了，沒想到收到這個email
