My 22-years-old son holds an Italian student "varsity" card.
Actually's living in London and has been denied a "Discount
Travelcard" because is supposed to be "Only available to holders of a
valid Student photocard".
Somebody can confirm if a foreign student card isn't a valid one?
Thanks

No, it's not valid for getting a discount Travelcard.
He will need to get the correct form from the college he is attending in
London. This should then be sent, with however many photos they request,
to the address on the form for the issue of a Student Photocard.
These are NOT issued at tube-stations BTW
