HELP - What paperwork for flying between States in US for Student?

[SortCode]

DS is flying between States this week and his contact has sent me a message asking for copy of his visa (F1 Study visa). What do I send...is it:

Copy of the F1 paperwork that his school raised
AND I also have a copy of his visa within his passport

I took copies of all this before he left!!! Surely they dont need anything else for the visa side?????

I think it must be just the F1 paperwork

Americans flying between states have to have ID with your photo on.
So maybe he needs to use the visa and his passport together. I'd send copies of both just to be sure.

His passport has photo id plus tge visa page does too
