Visa
 

How do you do with VISA, if you spend 4-5 months going around in South America. And returning to same country.
Example.
Chile-Peru-Bolivia- Argentina-Chile-Argentina-Chile over a 5 month period.

On VISA for every visit to a country ? For "enough time for that particular visit
A 90 day VISA will expire before end on trip.

Thanks

You get a new visa each time you enter.
