The major difference between the Estonian digital nomad visa and a Schengen visa is that the DNV is specifically designed for digital nomads or remote workers, offering long-term remote work benefits for one year. In contrast, the Schengen or Type C visa allows non-EU nationals to enter Estonia for short-term stays of up to 90 days within 180 days for tourism or business purposes, but does not permit employment. The main differences between an Estonian digital nomad visa and a Schengen visa are the purposes, visa durations, and work authorization requirements.
