If you are planning to visit Sweden temporarily but to stay longer than 90 days in a six-months period, you should apply for a visitor's permit.
Visitor’s permit is a residence permit for visits. An application for a visitor's permit is always sent to the Migration Agency in Sweden, where the decision is made. If the application is granted, a residence permit is usually issued for more than three months and up to twelve months.
In order to be granted a residence permit to visit Sweden, the purpose of the trip must be to visit Sweden and not to settle there.
Applications for visitor's permits are handed in digitally. Apply and pay the application fee by using this e-service.
When you conclude your application in the e-service, you will be directed to a page where you book an appointment for a physical visit at the Consulate General. During this visit you will show your passport and conclude your application with an interview. You will also give your fingerprints and have your photo taken.
A national visa (D-visa) is only issued in exceptional cases. According to the law, special circumstances must apply in your case.
Note that a family visit is not considered special circumstances. The fact that you have previously been granted a D-visa does not automatically mean that you can get a new one.
