I want to ask one thing about getting a business visa. I have got a Pakistani passport and i have been living in Turkey for the past 5 years. I just finished my studies so i want to move to Czech republic for doing some business and possibly getting a permanent residence there. I have got an invitation letter from my friend and i can stay in Czech republic for 30 days on the short stay visa. My question is that is it possible to apply for a business visa from inside the Czech republic or do i need to get it from here before entering Czech Republic? Thank you in advance for your help.
