In order to be granted a residence permit as a visiting researcher in Sweden you must show that you have a hosting agreement with an approved research organisation. It must be signed by both parties.
When you apply for a residence permit you should provide the following documents:
You can apply via the Swedish Migration Board’s website www.migrationsverket.se, or at the Consulate General in Guangzhou. Please note that if you hand in the application at the Consulate, you need to do so in person.
The application fee for applications handed in at the Consulate is 1770 RMB. The fee will not be refunded if your application is rejected.
The Swedish Migration Board decides on residence permits. The permit must be entered into your passport before you travel to Sweden, which means you cannot travel to Sweden and wait for the decision there.
