Great info on passport options. Often the best one to have is the one that is not your original country nor the one in which you reside. Of course, the US passport comes with a lot of strings attached, so make sure you're willing to become the property of US Inc before signing the line (if you have a ss#, you already are, so might as well get the passport).
How come Latin American passports were left off the list? Oceania is missing too. There are some good options there.
