Pasengers: Myself (US), my wife with different last name (UK), my daughter with my last name (US) and my step-daughter with same last name as my wife (UK).

April in ATL: Wife-to-be and myself in same citizens/residents line. I got "please step back sir" while I take care of her.

April in AMS: Now married. Same line, EU Citizens. Very unhappy agent. Acted as if I should be detained for being in the wrong line. Mainly because in AMS, they think permanent EU residents need stamps and the EU line agents don't bring their stamps to the booth.

Nov. in ATL: Now married, but no change in paperwork. All of us in same line. Agent directing people frowned and implied that we would be sent back because even 1 of us was not a resident or citizen. Passed no problem as a family unit.

Nov. in BRU: Agent directing traffic tells us we could have gotten in the EU Citizen line. Passed as a family.
