Thank you MaineShark and winterboarder for your replies.
I realise now that my approach was a bit defeatist and perhaps too accusing, mixed up with an air of asking for a service rather than providing constructive criticism (which actually was my ambition). I am not in any way asking for the FSP to become an immigration service, I more or less wanted to point out the possibilites of marketing FSP globally, for reaching the greatest amount of liberty-minded participants. I still believe that this opportunity is not marketed as much as it deserves, and my query was a way to try to find out the motivation behind this. I assumed this was not something that had just been forgotten about or not observed, I got the image that this was underreported for a reason, and wanted to spark a debate to see what could or might be behind this.
What I was leaning towards suspecting was that the image of the stereotypical (if there is one) non-US-citizen and his expected political leanings was standing in the way of the ambition to promote with full force the FSP globally. To make a strawman of both sides of the spectrum would mean that the typical European is seen as the gun-hating atheist and liberal hippie (who still for some reason might be genuinely interested in the project), or the introvert communist from certain parts of Asia, the non-integrable Third-World citizen, etc etc. I do not believe this is what any of you picture when you consider non-US-citizens, because I'm taking it too far (intentionally, to make my speculation clear as possible), But still I wanted to bring up the question of why this opportunity is not, in my eyes, not as profitably taken into consideration as it could. There is somewhat general advice on the main site for how to move (from one part of the US to NH) and what to do when you're there, but in case I missed it I don't see anything similar for the rest of world. As you guys have already pointed out there can be no general guide for 7 billion potential participants from more than 200 different sovereign nations, all with different rules and regulations regarding immigration - but is there an ambition to, at least in the future, provide something that would be a broad sketch of what one might expect to happen if one plans on joining the project from abroad?
Regarding my strawman of the stereotypical non-US-citizen my point was also to try to debunk that, and rather point out that there could possibly be millions of already-integrated-to-the-situation potential participants all over the world, that today might lose out on even internally brainstorming the idea of joining the project because it seems too far off, in practical terms. Perhaps a general discussion about this could help them feel the urge to investigate further, what they could do to join in. As I said, I assume there are more (in numbers) wholeheartedly motivated potential participants spread out over the globe than there are in the native US-stock in total, and wouldn't it be nice to gain the interest of as many of them as possible? Let's say that even if only a few percent can find their way to the destination and be able to legally stay there, that would still be a huge number in total. To me it seems that would benefit the project immensely.
