The Colombian student visa is a Visitor (V) visa for foreigners enrolled in an accredited Colombian educational institution. Universities, language schools, vocational programs, exchange programs, and postgraduate courses all qualify, provided the institution is accredited by the relevant Colombian education authority.
The visa is granted for the duration of your course and is renewable as long as you remain enrolled. If you are from a visa-exempt country and your program is short, you may be able to study during a standard visa-free entry (up to 90 days, extendable to 180); anything longer, or any formal enrollment, requires the student visa.
