How does a US citizen _look_? Last I checked we were an incredibly diverse nation.
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.
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.
