Hi Guys, I went to interview on 27th Feb. VO asked me couple of questions and gave 221g blue slip and told administrative processing is needed. He kept my orginal I-797 document and client documents and told they need to verify client. And told it will take couple of weeks and will everything is ok, we will ask you to submit your passport. But till now I didn't have any update. How they will contact us.. will they send any mail.
