Marry and naturalize with Swedes

If you want to become a Swedish citizen, I suggest you get married in Sweden, because naturalization requires relevant certificates, such as marriage certificate. They won't understand if you take China's marriage certificate. Also, it seems that if a non-Swedish man marries a Swedish woman, he can get a permanent residence visa immediately, that is, a green card. But if a non-Swedish woman marries a Swedish man, I am not sure.

I also want to know this question, hehe. I'm a Swedish citizen, and my girlfriend is going to get Hong Kong citizenship in China. She will come to Sweden to study later, and I also want to know about the visa, hehe.

I heard that there is another kind of visa called Sambo, which is the cohabitation visa. You can use it to come to Sweden first, get married and then become a citizen.
