I spent a bit of time tonight looking at the Estonia’s Digital Nomad Visa requirements and I do believe the idea of applying for a Estonian Nomad Visa then heading over to the Netherlands is possible.
From the Estonia Digital Nomad Visa FAQ.
17. How long can a DNV-holder stay in other countries in the Schengen Zone during their visa period?
This depends on whether you have a short-stay or a long-stay visa.
For example, during the validity of an Estonian long-stay visa, the holder can stay in other countries in the Schengen area for 90 days within 180 consecutive days.
I looked at the Schengen area and found the above mapping. I’m sure its obvious for most but I hadn’t actually looked at what countries were included and not. I can imagine a base out of Tallinn, Estonia and a month or two out of the Netherlands?
The other restrictions look good to me although I’m also interested in the short 90 day Nomad visa too.
