But I'm worried by the first move. Where I live I got a lot of job opportunity but I don't know if I will be able to find a job in another country quickly enough and it doesn't work very well remotely.
If you have a popular web service or a iphone app you could do it.
Since you just got your degree, my honest advice is this: 1) Be slow to accumulate stuff. 2) Exploit the location where there are a lot of jobs, but do it in a way that doesn't tie you down for 4 years. Do consulting or contracting, or become a co-founder of a startup that is a virtual company such that the company isn't tied to this location. You need some good work experience, which you might have gotten while getting your CS degree, but if not, get it, and get some savings to boot. 3) Start practicing it. Start working away for a week at a time.
Unless you're independently wealthy you can't really spend your time without any work, so the challenge is working while you're a nomad.
