So I just arrived in Santiago this afternoon, and wouldn't you know it... my passport was the wrong color. So I trudged over to the desk to pay the reciprocity fee.
I noticed that the person who processed the payment stapled a receipt to the last page of my passport.
I thought that was a little odd, so I looked more closely at the receipt:
VALIDO HASTA LA EXPIRACION DEL PASAPORTE
(valid until the passport expiration date)
Am I interpreting that correctly to mean that I now no longer have to pay the reciprocity fee when I arrive at SCL airport with this passport?
