Effective December 28, 2009 Citizens of the U.S., Canada and Australia will be required to pay a fee when entering Argentina.
The government of Argentina will collect an entry fee as the following:
The entry fee will be collected only at Buenos Aires Ezeiza International Airport (EZE).
The payment of this fee is not a Visa since Argentina does not require a Visa to citizens of these countries when traveling for leisure or business travel. Once paid by U.S. citizens, the fee permits multiple entries into Argentina for ten years in accordance with U.S. Visa reciprocity. Americans may pay in U.S.dollars, Agentina pesos, by credit card, or with traveler’s checks.
NOTE: (Canadians and Australians must pay a per-entry fee.)
If you have any questions or for complete details about this entry fee, visit the U.S. Department of State website at: http://argentina.usembassy.gov
No visa is necessary when you travel to Chile, only a valid passport. When entering Chile (By cruise, vehicle or plane), at customs, you’ll need to fill out a Tourist Card that allows visitors to stay for up to 90 days and will allow multiple entries. You’ll need to show this Tourist Card to Customs when leaving the country as well, so be sure you don’t lose it. For more information on other type of Visa, go to the CONSULAR SECTION.
There is a reciprocity fee of US$131 dollars to be paid in cash (U.S. dollars) or credit card. The one-time charge is good for the life of your passport. Go to the CONSULAR SECTION.
