Permanent residence - live in another country
What if I have a permanent residence permit but wish to work/live in another country?
You may leave Sweden for up to two years without your permit being suspended. However, you must notify the Migration Board of your stay abroad in advance, no later than one week prior to departure. If this notification is not made, your permanent residence permit may be revoked if your stay abroad exceeds one year.
If the reason for travelling abroad is that you are a civil service employee in Sweden and posted to work on behalf of your employer, special rules apply.
