Once they send it to the embassy, the embassy will send u a Packet 4 email. If they don't automatically give a date for interview in that email, u need to create an account on the USTravelDocs website to pick ur date faster. U can only check for appt twice per day. If the Petitioner is in the US, they can call numerous times at +1 703-520-2575. My husband kept checking the website for 9 days with no luck. I called every 15 minutes on one day and got us an interview date
