Which school do you want to study? What program can you take? Are the schools offering scholarships?
Having summer or part-time jobs for students is common for students in Czech Republic. There are options for international students as well but are limited as most of them require workers to be fluent in the Czech language, however, many international companies in big cities value employees that are able to speak in multiple languages.
Students from the Philippines also don’t necessarily require an employment permit, under certain circumstances.
Czech Republic is landlocked in the center of Europe with neighboring countries like Germany and Austria. This gives off more opportunities to work after studying. Start ups are becoming popular now among Czechs with also a fill of big international companies. If you do decide to work or stay awhile in Czech Republic, the cost of living isn’t too much either.
