it is up to you if u want to import a guy from half way around the world but believe it or not you will only serve as a ticket meal to US. I mean those guys from thailand or Loas they still live in a very tradditional lifestyle; they only want to marry those proper girls. by buying them off, they would view you as an improper girl. Plus the majority of the guy they want to marry someone who is very young, in their early teen. seriously, I don't think you will be able to find true love with those guy there, it is one in a billion chance. There is this one girl who is just 21's and she import a guy from Laos;he doesn't want to marry her from the start but just used her as a meal ticket. He doesn't work, so she has to support him and everything.....geezzzz...
30s is not that old, and I'm sure if you give the time, you will fine someone better than those from thailand or laos.
