Following an article in Takeoff I check the interesting work that the countries of South America are carrying out to facilitate travel procedures among their citizens. The objective is that South American citizens can visit the other countries of the southern part of the continent without the need for a visa or passport, simply with the ID or ID. The only countries outside this block are Guyana and Suriname.
This is a process that will be taking place during the next months as it requires bilateral agreements that guarantee reciprocal rights although some governments have already put to work. As an example, Peru already admits Argentine, Bolivian, Ecuadorian and Chilean citizens possessing only DNI and a return ticket.
If you plan to travel in South America in the coming months it is convenient that you take a look at the requirements to embassy or consulate on duty in case the passport is still necessary.
It is really good news that will help improve mobility between countries and facilitate the work of the traveler.
