She says your first stop should be the trade license office in city hall. Previously, you had to go to “your” district (i.e., you live in Prague 4, you had to go to the Prague 4 municipal office) to take care of business, but the new changes say you can now apply at any trade license office in the city. Here, you can chat with the people who will be processing your application, pick up any needed forms, and do a walk through of the process before you get started. In a typical bureaucratic way -documents, signatures, stamps, etc. may differ from office to office. Checking first will save you time and headaches.
