What is difference between Sambo visa and residence permit ?How to get them?

After two years, this temporary residence permit (Sambo visa) can be converted to a permanent residence permit.

Sambo visa means that you can come to sweden on sambo visa to live with your fiancee who is a Swedish citizen. Sambo visa will depend on the Immigration when your fiancee apply for a sambo visa for you. When you arrived in Sweden on a Sambo visa, your fiancee shall apply for a residence permit for you to stay until you get your permanent residence after 2 years of living together if your relationship is without having any issues. I hope this helps.
