Also, it's true that many countries will not want you if you have any type of chronic medical condition, to become a citizen. I joke all the time about moving to Canada, but they won't take us. I know this because I know a lady who has diabetes type 1 and can't afford insurance, so she looked into moving to Canada and right away immigration told her that she couldn't because they won't add her to the national health. That's for either people who already moved their before they were sick, or born there. It's like a pre-exisisting condition clause....
