I would like info

I am a Greek-French-American. I am a U.S. Army Combat Veteran and in 2024 I got out. In 2025 i moved back to Greece to pursue becoming an electrician. I have come to the decision that I do not want to work/live in Greece. I have decided that Czechia would be a nice place to move to when I get my electrician license. I am planning on learning the language as best to my ability and history too. I am not planning on being some dumbass immigrant that longs for his country. I have many questions about Czechia and I would love to get them answered. Would anyone be able to unload anything that is good to know for someone planning on moving to somewhere not too far from Prague but not inside. What should I expect.
