Sure.....just marry a nationalist of that country and BAM! You are nationalized! lol

No all kidding aside. I have been told by a friend that in Malaysia or Thailand that once you deposit like $80,000 in their bank, they will grant you citizenship. I have not had time to do the research but a few of my friends have citizenship in both these places.

Another cheap way is to do a business in a country and you can eventually nationalize through time.
