If you are a student who is interested to work and study in Prague and are not holding an EU passport then your options are limited in what you can do for a job in Prague. Having a part-time job which pays around 80-120 CZK per hour is obviously not an option as a means of paying your way through a study program. Of course, if you are a citizen from a non-EU country and you want to work and study, you can, but living in Prague on a study visa, your part-time job cannot be a full-time occupation during your stay.
