I submitted an F1 visa application for a family friend around 10 days ago, to the Recife, Brazil consulate office, and it still won't show me the application status when I enter all the details at https://ceac.state.gov/CEACStatTracker/Status.aspx?App=NIV. I put in what I believe is the correct information (which I got from the receipt e-mail when I submitted the application) and always get "Your search did not return any data." Should I worry about this, or does it take time to show up in the system? Thanks in advance for any help!
