I'm non-EU citizen doing a postdoc at a US university, and I'm not from one of the countries with a relatively strong passport. My goal is to get a job in a EU country that issues a Blue Card and eventually get myself one. I'm trying to see here if I can get closer to my goal by taking the following route: suppose I get a position as a researcher with more than 400,000 annual DKK salary. (I've good chance in getting that). By the "pay limit scheme" mentioned in https://www.justlanded.com/english/Denmark/Denmark-Guide/Visas-Permits/Residence-permits, I can get a Danish work and residency permit. However, my goal is to move outside DK and get a position in EU minus DK in the first year itself. I'd like to know how much mobility does the Danish residence card holders have.
My question is: if I terminate the job contract in before the end, will they terminate my Danish permit as well after 14 days? Or will it still be valid? In the second case, can I use this Danish permit to search for jobs, say in France?
