Here's the email I received Thursday:

Good Afternoon,

A reminder that we need a copy of your passport, city of birth, and any documents that have been renewed since your interview date (i.e. medical, ATP). If you have any questions please reference the 'Important Information and Instructions' attachment that was sent to you by Interviewer Assistant in your Class Offer email.

Please send them as soon as possible, as you are starting class next week on the 1st.

Thanks in advance,

KK
