An illegitimate minority?

I'm seriously considering checking the "Other" category on any form that ask for my ethnicity (other than those where I might get in trouble from the Feds), then writing in Australian-American, for that's what I am. I think if someone whose family has never set foot outside of the U.S. anytime in the last 200 years can claim to be an African-American, I, who have only been here in the U.S. for 8 years, can call myself an Australian-American.

I'm an American citizen but I don't think like an American, but after being here for eight years I also no longer think quite like an Australian. I'm not an American, and I'm not an Australian; I'm an Australian-American. In fact that's legally correct because I am a citizen of both countries.

I'm sure I'll get funny looks from some people, but I'll just explain that while I may look Caucasian, I'm actually an Australian-American.
