Will I be able to join. And if not why?

I'm very eager to play in the tournament. Thats like the third year and my country is not able to participate for some reason.
They say it's because of some law. I don't buy this because poker tournaments are allowed here if there is a law for "gamble" or something, it won't count for this tournament definitely.
What I've also heard is that only a few countries are eligible to play. Thats because there is a blizzard department there.
I am not sure which is right or wrong.
But I would like for once a good explanation (from gm for example) exactly which countries are allowed/not allowed and why. And also if there is a way to participate no matter my country fails or what ever.
