Student license - how long it takes?

Hello there!
I would like to Ask you, how long it takes to get student license? I am waiting for 24 hours and i don’t have access. I need this software to complete my thesis, so I really hope to get it as soon as possible.
I have also a question about duration of student license - is there way to use it for more than 30 days? I will probably need it for 60 days.
