Official transcript at time of application - Duke? Others?

DS is going to send in his app soon to Duke RD. It looks like they want the official transcript sent from the counselor at that time. Does anyone know if this is correct or if the self reported information on the common app is enough for now?
Are there other schools that will only consider application with official transcript?

The transcript can be sent after the application but before the due date. Most colleges give a few days grace period for things like recs and transcripts.

If he hasn’t submitted yet but school goes on break tomorrow, can it be sent today - before his application?

Also, the counselor has already attached the school report and her recommendation to his common app. Would the transcript be attached there? I sent DS a text to go talk to her so I don’t know yet.

Yes.

Thanks!
