IRS nightmares: My tax return is 'insane' - Jul. 1, 2014

Watchout. It is not as easy as you may think. Read this article. The US is one of only 2 countries in the world that does double taxation on it's citizens. Also if you have a foreign spouse thats does not even have a green card they will want to know all their assets and income, you will pay taxes on it too. If you buy property overseas there is a huge problem if the exchange rate changes and you show a profit in USD even if you have a real loss in local money.
