Ecuador is easy the first 90 days, and Panama the first 180 days, but basically all Latin-American countries have complicated and expensive immigration systems that require lawyers and stamps for every single thing. It easily costs thousands and thousands of dollars, lesson learned.
As bad as the situation has become here in Suriname, we have managed to file all of our own paperwork and arrange every document we needed in person without ever paying a fixer or translator. Our whole immigration process here hasn't cost more than $300 USD.
