I had the same fears when I sent mine out, but don't worry because it usually takes between 7-12 days. When I sent mine out on the May 31st and June 4th, they were received by the 11th and 14th respectively. If they don't show up today or tomorrow, definitely expect them by like Wednesday next week.My school said they snail mailed it out on the 10th. But AMCAS hasn't received it yet and they're processing transcripts received on the 17th yet. I feel like mine should've gotten there by now because I snail mailed another one from a different school the day before and it was already received a few days ago. I'm just afraid if it got lost in the mail or something.
