Huh? There is more than one TLD. .us is available for US people. Every country has a TLD. There's a whole pile of generic TLDs. Finding one for you will not be a problem.
You have to realize that the general public doesn't always understand that the internet isn't always .com.
My email is josh@josh[dot]micronesia. When someone — such as a banker, or "everyday" person — asks for my email address, I overwhelmingly hear, "josh at josh dot m n at... what? gmail dot com? yahoo dot com?"
The repetition probably confused them, and it also doesn't look that nice. If you use something like me@josh[dot]micronesia I'm sure you would be met with much less confusion.
I bought a 2 letter domain on a .vg and a .mg TLD. It's amazing how many websites refuse my l@up.vg email address on signup as "not a valid email address".
