Chile Forum

Hi all, I just got my Chilean nationality processed and now am in possession of my cedula de identidad. I read on the Registro Civil's website that all I need to travel to any MERCOSUR or associate member state is my cedula, that I do not need a passport.
Are there any reciprocity fees for Chilean citizens in these states?
Are there any restrictions on the amount of time I can spend in these countries as a Chilean citizen (do I need to apply for any type of visa, residency, etc)?
Thanks so much!
