"when does anyone become American?"
Depends on what the meaning of "is" is. There is genetics, there is nationality/citizenship, and then there is a civilizational [sociological] affiliation. Genetics one cannot assume, nationality/citizenship is afforded by the others, civilizational affiliation one could assume [or discard and change, with some effort] all by oneself. So which one do you mean by an "American"?

[It's me]

I was asking "DTA" because he/she said

Nope, he is Slovakian-born Czech."Slovak" is ethnicity, Slovakian is citizenship. Being born in one country does not make you member of people living in that country, but make you citizen.

My parents were Czechs but they moved to Los Angeles- to America- in 1958 and I was born in 1960 in Los Angeles.

So I was asking when do I get to be an American by his/her standards. I am an American born Czech but I am American.
