If your visa application has been refused, it's possible to appeal the decision. You get information in the decision as to why your application was rejected. If you received a decision you are not satisfied with, you can submit a written appeal no later than three (3) weeks from the day you received the decision.
If more than 3 weeks have passed since you received the decision, the appeal will be rejected by the Embassy.
Please write your appeal in Swedish or English.
Do not send your appeal several times or in different ways.
If someone else (other than you, the applicant) signs the appeal on your behalf, that person must be authorized to represent you with a power of attorney.
If the Embassy finds that the decision should be changed, you will be contacted. The decision can be changed if you provide new information or if the Embassy considers the decision to be wrong.
If the appeal came in on time and the Embassy sees no reason to change the decision, the case will be forwarded to the Administrative Court in Stockholm as soon as possible. Your application, the decision, and all other documents submitted in the case will be sent to the court in Stockholm. The court then makes a decision and notifies you at the address you specified in the application or in the appeal.
After the case has been handed over to the court, all questions about the case should be addressed to them. You find their contact information via the link here.
After receiving the appeal, if the Embassy wants to change its decision, you will be contacted in a few working days. If the Embassy decides not to change its decision and forwards it to the court in Stockholm, the waiting time would be longer.
