Am I obligated to purchase full version CC and then apply for one with student license by sending important documents to approval from Adobe? If it´s passed, Adobe would give me a refund or something? Just in case, it is important- I´m from Slovakia and I study in Czech republic at the university. Thanks
Unfortunately we do not currently have a student/teacher option in all countries including Czech Republic - see the FAQ for availability - Creative Cloud Help | Creative Cloud / Common Questions
You can sign up for the full version but I'm afraid there would be no discount or refund.
