Please how would I reschedule an appointment at the Nigerian embassy in DC for passport application? The date I was given when I made a payment online is not favorable.

So u can walk in without an appointment?

After trying multiple times, someone in the admin department answered and informed me that the dates in the application are randomly generated and so you can come in any day after your appointment date and get attended to. PS: make sure to buy a prepaid return envelope so they can mail you the passport once they are done because you won't be able to pick it up the same day.

I'm still seeking a possible solution to this situation.
