@Andre10024 You can't change it. Airbnb allows 24 hours to verify a guest's information. So if you accept the booking request, you may have that wait.
Of course this isn't fair to hosts. Guests should have to have all their info verified before they are allowed to send a booking request. But Airbnb doesn't want to make anything at all difficult for guests.
I have found that when a guest has a history of Airbnb stays, their booking gets confirmed right away, because all their info is already verified. It's the new to Airbnb guests who it can take this time with. So you could just start declining all requests from new users, but that's not a great alternative either.
Some hosts have reported that they insisted that Airbnb that the block be removed, that they couldn't be expected to lose out on bookings just because a guest didn't have all their info entered, and were successful.
