"beat the system" tip 17: beat the long foreigner lines at passport control
 

a) fly the foreign airline (nationals tend to fly them, there will be less foreigners in concurrence to you)
b) use the foreign airline terminals (in lager airports): but only with hand-luggage.
c) link up with a national you meet on the plane
d) get to the foreigner line first
e) choose the fully-manned two-window booth
f) choose the line next to the National-line. When all the Nationals have passed that line may change into a foreigner one (always at UA's IAD-airport!).
