Hi everyone, I have been following the blog, thanks for the information. Unfortunately I still haven't received the bio letter, I have received E acceptance last Thursday, may I check if online case status should say bio letter was mailed, right now it's says acceptance of biometric fee and application being reviewed at Nebraska service center, do they send bio letter?should online status say bio letter mailed? And baltimore office send interview letter? I am in MD. I understand I should not walkin without a bio letter , correct ? I was thinking to call their number, pls help, thanks
