The most important piece is missing: Is the digital-nomad visa holder a subject to Colombian income taxes? I read wildly different opinions on this. Most sites say the visa holder can't stay in Colombia more than 183 days/year, otherwise triggers residency tax. What would be the point of the visa then?
It is always a pleasure to help! To be eligible for a Digital Nomad visa, you must hold a passport issued by one of the countries or territories exempt from short-stay visas, according to the Resolution. You can find the list of the countries in the following link: nexo.legal/home/colombian-visa/
