What procedures do China girls need to go through to get married in a foreign country? Do you want to emigrate

You don't need this. Registration in Singapore requires a passport, which is not recorded in China. If you want to immigrate, it will take several years after you get married. According to national regulations, there is no need for immigration. I have a friend who got married in Thailand and is still a foreigner. If you want to emigrate, emigrate, not at home.
