We lose about $1 trillion a year because of this silliness and you're telling meit's a joke? Lost business, multi-hundred-million dollar errors (conversionerrors are common but usually not as spectacular as the Mars mission) andwasting vast amounts of time/money dealing with two systems.  This is costing us far more than immigration issues, it's just less obvious than a guy inhandcuffs.  It's really time for us to finish the job and relegate our customary system to the annals of history.
