To be able to be granted a work permit you need to have an offer of employment. You are in most cases not allowed to start working in Sweden before your work permit has been granted.
There are several different kinds of work permits, e.g., for artists, au pairs, berry pickers, visiting researchers and athletes. For details, read the information on the Swedish Migration Agency's website. The website also describes exemptions for certain occupational groups working in Sweden for a limited period.
Citizens of the EU/EEA
As an EU/EEA 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 Agency's website.
Residence permit card
If you are granted a permit for more than three months, you are issued a residence permit card. The card is proof that you possess a residence permit. On the card it is specified where you are allowed to work and at what profession.
You can also find more information about the residence permit card at the Swedish Migration Agency's website.
If you obtain a permit to work in Sweden, your family member (spouse or unmarried children under 21) may be granted a residence permit for the same time period. If you receive a permit for at least six months, members of your family can also obtain work permits.
