LAX Immigration and Customs, first time:
“Have a nice stay, enjoy California!”
Second time:
“Are you on vacation here? Allright”
Third time:
“What are you doing here? Where’s the plane ticket to get back to your country? What are you doing here? Why staying for so long? Let me see your card. So why are you coming here?”
Immigration. It seems fair until you’re on the other side.
