In January I'm starting a 6 month trip of Central and South America starting in Panama. I plan to travel down the west coast of South America and don't have a return flight back to Canada because I don't know when I will be leaving. I've heard you must have a ticket out of the country to enter most countries. What is the best way to go about this? Some people have said to just buy a $10 bus ticket out of the country so if you don't use it, that isn't a big deal or loss of money. If I had a return ticket from, say Venezuela to Canada, would that work in every country I visited or would I need a specific ticket out of each country. For example, when entering Panama having a ticket to Colombia, then when entering Colombia having a ticket to Ecuador, etc etc.
Thanks for your help!
