I am a bit confused about traveling as a researcher in Schengen countries. I am a citizen of the United States, but have a residence permit to live in Finland. Based on the immigration office here, this means I can spend 90 days out of any 180 day period in any Schengen country without a visa.
However, does this mean that I can apply for a visa as a researcher in a Schengen country and not violate the rules of my residence permit? I talked to a person at migri (immigration office; https://migri.fi/en/travelling), and they suggested that I temporarily emigrate, and then I can be on a researcher visa in the other Schengen country without it counting against the Schengen clock. Has anybody else gone through this?
