Employed researchers, non-EU/EEA/Swiss citizens

Visiting Schengen/DTU more than 90 days
All employed researchers with a non-EU nationality—visiting Schengen/DTU for more than 90 days—must have a valid work and residence permit before they start working at DTU.

Visiting Schengen/DTU less than 90 days
If the employed researcher is visiting Schengen/DTU less than 90 days he/she may come to Denmark and work at DTU without a Danish work and residence permit, provided that the researcher will not be in Schengen for more than 90 days in any 180-day period (including day of arrival and departure). Note that previous stays in other Schengen countries have to be included in the calculation.

Please use the Schengen Calculator in case of doubt about the 90/180-day period.

If the employed researcher is a citizen of a country with a short-term visa requirement to enter Denmark, he/she must have obtained a visa valid for the entire stay before entering Denmark.

If the stay in Schengen is expected to be more than 90 days, the employed researcher must have a residence and work permit covering the entire period, including the first three months. The work and residence permit must be issued prior to arriving in Denmark.

Accompanying family members
If the employed researcher holds a residence and work permit, he/she can usually bring his/her family to Denmark.
