I have been working as an academician in a EU country. I am planning to complete my 5 years to apply for permanent residence. However, later in my career I want to return back to my home country, which is non-EU. I am worried that in this case my permanent residence will be canceled after a certain period of time if I continue to live outside of EU (link to the information). And, the same thing applies to the ownership of EU Blue Card (more info here).
From this, I conclude that it is not possible to maintain permanent residence in EU if one eventually plans to live in his/her home country that is non-EU. Only way seems to having citizenship of a EU country. I wonder if I have a lack of information on this. Anyone has something to add and share?
