(warning: very long sentence LOL) If you like Colombia and you want to live a few months in Colombia every year, but less than six month because you dont want to be considered a resident and pay tax there or having to deal with the colombian government other than tourist visa related things, as your main country is elsewhere and you are registered there as a resident so you are not going to register in Colombia, but still you live there a considerable part of the year so you want to be able to do stuff like:
- open a bank account
- rent a flat
- buy real-estate
are you allowed to do any of those things and with which visa and how to do it?
