You must have been offered a job before you can obtain a work permit. Your work permit must have been granted before you leave for Sweden. If your job is for less than three months, you may also need a visa.
There are several different kinds of work permits, e.g. for artists, au pairs, berry pickers, visiting researchers, athletes and coaches. For details, read the information on the Swedish Migration Board website. The website also describes what exemptions apply in the case of certain occupational groups working in Sweden for a limited period.
As an EU citizen, you are entitled to work in Sweden without a work permit.
Special rules apply if you have a residence permit and long-term resident status in another EU country.
Read more about the rules for EU/EEA citizens and long-term residents of an EU country on the Swedish Migration Board website.
If you are granted a permit for more than three months, you are issued with a residence permit card. The card is proof that you possess a residence permit. Read more under ‘How to apply’ to find out how you arrange for the card.
You can also find more information about the residence permit card on the Migration Board website.
If you obtain a permit to work in Sweden a family member (e.g. husband/wife and unmarried children under 21) may be granted a residence permit for the same period of time. If you receive a permit for at least six months, members of your family can also obtain work permits. Family members who are granted a residence permit need a residence permit card (see above).
