Adjustment of Status - I-485

So today I went to my second interview in Chicago I live in Indiana and it was very very bad on the road Because of the snow it's take from us so long to arrive there
Our interview supposed to start at 9 And the lawyer says maybe they will separate us because it's second interview
We wait like one hour Then one of the officers called us He was very good man
But he was mad because he told us they supposed to close today
There is a lot of officers they didn't arrive to the building because of the snow
And my case is not with him but the supervisor told him to take this case
He told us he didn't know anything about our file it's too big and he need like 10 minutes to look through it
Then he was wondering why it take more than 2 years without Decision
We told him we call a lot but no answer they only keep saying pending review
There was a big file in front of him and I gave him a lot of papers too
He didn't ask us anything
He says they're supposed to give you an answer long time ago I don't know why they keep you waiting
Then he told me I can give you Proov for your green card now but I have one issue that you have expired medical test
He told me just go back home and do your medical test and send it back to me and I will approve it for you right away
It was very long journey starteded like more than three years ago
I can't believe until now that they will approve me until i get it in my hands
