Dear VO,
I am trying to schedule a regular interview for an F1 visa but the portal is not bringing out the calender like image from where I can select a date from the options. Please how many days does it take to after payment of visa fee before scheduling appointment for a regular visa interview.

please I need someone to guide me properly. After payment of the Visa fees at the bank and filling the 1-20 form, how long should I wait before scheduling a regular interview. This is because I noticed that the calender-like image that pops up to enable me select a date for interview is not coming up? please.
