Via Lucky, I just found out that Argentina, for the next 90 days, is waiving the $160 “reciprocity fee” that it normally charges US citizens upon entering the country! Here is the full, official text:
Reciprocity fee for US citizens
In order to strengthen the relationship between Argentina and the United States of America, the Argentine Government has resolved to suspend the collection of the reciprocity fee from US passport holders who visit our country for less than 90 days, for tourist or business purposes.
Buenos Aires, March 24 2016
Once paid, the visa was valid for 10 years, but it was still extremely annoying to have to pay to visit a developed country like Argentina.
The new policy will translate into a direct savings of $160, each, for my sister and my friend, who are coming with me next month to Buenos Aires and Mendoza.
Hopefully, Argentina will continue the policy after the trial period is up, but politics are utterly crazy down there, so, we shall see!
