Adjustment of Status - I-485

So, I had my interview this morning. Everything went smooth. The IO is an old nice man, he even helped to make some copies for us (there is our house title I forgot to make a copy). He didn't ask much, just some basic Yes/No questions on the documents, name, address. That's it! Then he went out and came back, gave us the notice that my case is under review. He told me that I will receive a mail in 2 weeks and asked if I know how to renew my 2 year green card before it expire. My attorney said she knows it so he said" okay so your attorney will let you know". Then we left. My attorney told me that she think I will get approved.
So, I keep checking my status but nothing has changed yet. Anyone knows how long it would take for the USCIS update your status on the website???
