ok ive been reading that you need an onward ticket to get a visa for some countries such as brizil. im planning on flying one way to peru and travling over land the rest of the time has anyone ran into any problems doing this? if so are their any ways around it?
No problems without a ticket. I doubt they will ask, I never got asked. Without a ticket, if you can prove that you can support yourself (i.e., flash them a credit card), then you will be fine.
Another option would be to buy a fully refundable ticket from Peru to another country. Just in case... Once ur back home u can get ur money back. I dont know how long u plan to travel but u might wanna check if there is a time limit on the refund e.g. within a year of purchase.
