Corrected entry: Both of Claudia's parents are in this episode, and they are obviously American. But in the episode "We Are Family", Claudia said that she is half-Italian. She can't be unless she has one Italian parent.
Eddie and This Guy with Diamonds - S2-E19
Corrected entry: In the scene where Sean, Eddie and Walt are playing pool, right after Eddie tells Sean "Women say they don't want you to get them anything, 'cause they want you to want to get them something, it's proof of your desire to please them", Sean calls Eddie by his real name and says "Kevin I'm terrible at picking stuff out for her, you know.". (00:03:55)
Correction: He actually says, "Yeah, but I'm terrible at picking stuff out for her you know", so it's not a mistake.
Correction: One parent could easily be Italian (born in Italy and raised in America or lived long enough in America to lose their Italian accent). In fact, in Claudia's mind, even if one parent was born in America, but to Italian born parents, she would still be half-Italian.

Yes. I think that Tony Bustamante, Claudia's father, is the Italian one. He could have been raised in America by Italian parents. This does raise a question of why Claudia's Uncle Sal Bustamante ("We Are Family" episode), looks and acts more Italian than Tony. But perhaps he is only Tony's half-brother - i.e, he might have lived with a parent and other relatives who Tony does not share.
