Hello.
I had my greencard via marriage interview on April 5th, and because it took so long for them to give me an interview date from when I landed in the US (18 months ago), my medical expired and they made me get a new one, meaning they had to issue an RFE. I went and got the medical, and posted it via usps. That was over a week ago, and my case status hasn't changed. Is this normal? The tracking shows my documents were received the day after i posted them.
