As soon as you receive your short-stay visa, make sure that all the information it contains is correct.
Check the following:
Do this yourself in order to avoid any problems or extra costs arising when using your visa. If you think that the information on the visa is incorrect, tell the Embassy immediately, so that any errors can be corrected.
''DURATION OF STAY.......DAYS'': indicates the number of days, you may stay in the Schengen area. The days should be counted from the date you enter the Schengen area (the entry stamp) to the date you exit the Schengen area (the exit stamp), i.e. both days included. The period of time between "FROM ...UNTIL" is usually longer than the number of days printed in the "DURATION OF STAY" field. The difference in period is meant to give you flexibility to plan your entry into and exit from the Schengen area, but your stay in the Schengen area must never exceed the exact number of days in the "DURATION OF STAY ...DAYS" field. No matter how many days you have stayed in the Schengen area, you must leave no later than the date printed in the "UNTIL" field."
Your short-stay visa allows you to travel to Sweden and usually to other Schengen States. But it does not automatically entitle you to enter the Schengen area. So you may have to provide certain information at border or other controls. You may, for instance, have to provide information on your means of support, how long you intend to stay in Sweden and why you are visiting Sweden. In some cases, such checks may result in a refusal for the visa holder to enter Sweden or the Schengen area.
It is therefore recommended that you carry with you copies of the documents which you presented when you applied for the visa (e.g. letters of invitation, travel confirmations, other documents stating the purpose of your stay). This will help to make the border control procedure easier and avoid delays at the border.
Please note: You must keep to the period of stay allowed by your visa. Misuse and overstay may result difficulties obtaining a new visa in the future.
