A Schengen visa gives you permission to enter and stay in the Schengen area for a short period of time.
Citizens of the following countries require a visa to travel to the Schengen-area.
Visas can be granted for purposes such as:
You can submit your application at the earliest six months before your planned visit. Apply as far in advance as possible.
A visa can be granted for between 1 and 90 days. You have to make use of these days within a given time frame of six months at the most (period of validity).
How many days you are allowed to stay in the Schengen area, and for how long altogether, is stated on the permit sticker attached to your travel document.
If you need to travel to Sweden or the Schengen countries often, you can apply for multiple entries and longer validity of the visa. At most a visa can be granted validity for five years. To make sure you do not overstay, please use the Schengen Visa Calculator: https://ec.europa.eu/assets/home/visa-calculator/calculator.htm?lang=en
A visa does not automatically mean you can enter the Schengen area. Border checks are always made at external border points. It could be favorable to bring along copies of the documents you submitted when applying for a visa. Border controls may result in you being denied entry.
It is the embassy or consulate that decides whether you are to be granted a visa. In certain cases, the matter is referred to the Swedish Migration Board for a decision.
