As I understand it, people from all over the world – with the exception of countries that send us more than 50,000 immigrants a year already – can enter a lottery to get a green card to come work in the United States. It’s purely luck of the draw, but once you get that green card, you’re basically free to immigrate here. The only educational requirement is that you have the equivalent of a high school education.
Are there other countries that have a similar lottery system? Many countries have point-based systems, but these tend to weed out everyone except people with graduate degrees or highly needed skills such as computer programmers.
