I just looked and there are exist stamps too (which implies an emigration check by the so-called investigative migration control police). My payment stamp/attachment has not been removed from my passports in 2001, 2002 or 2003. I don't recall having a Chilean tourist visa in my passport (just the entry/exit stamps which cannot be collected) so I don't know which tourist visas they are collecting; and the "gastos administravos cobro por reciprocidad" paper still remains. Maybe I just don't pay attention on those early morning flights out.
