The ferries to Stockholm is right around the corner. There are 13 software jobs to the dozen, you don't need any paperwork to work there, and €4k per month would be considered "bad" there. If I was in Latvia and spoke english I'd do it in a heartbeat. Even if I couldn't physically move, I'd definitely try to get a remote job from there even if it meant a slighly lower pay than an on-site one.

Obviously, you'd have much higher living costs and the weather would be slighty worse, but lets face it no one lives in Latvia for the weather either!
