I'm not sure if there even was an immigration, what I can conclude with certainty is that we were the only ones concerned with it.
@Bajo_cero2 - What's your take on the matter? Will they try to shake us down at EZE? Should we wear Sergio Dalma or Soda Stereo t shirts and carry a thermos of mate to increase probability of success? Any advice at all? We would have paid you but we couldn't find a way to contact you, so any information of your past experiences/expertise/etc on the matter would be greatly appreciated.
