Well, I meant what they think a US citizen would look like. For example, if you look Asian, you might still be a US citizen but more likely they'd treat you differently.

I'm saying this as someone who is married to a Mexican and crosses the US border by car. In general the experiences have been good by the way - just not all the time.

I'm just saying that it could be influenced by the way you look.

(not big in American ethnicity but)

I think his point is that "looking like a US citizen" is basically either being European, native American or African American. Which I guess is kind of like everyone except for people who look like Asian, South American or from the Middle East.
