What materials should I prepare for visa extension in marriage immigration?

Both marriage immigration and visa marriage apply for marriage certificates from two countries. Dual-certification visas are divided into tourist visas, business visas, family visit visas and reunion visas. What kind of immigration do you want to apply for is related to nationality. If you immigrate to South Korea, you will give up your China citizenship because China does not recognize dual citizenship, and once you acquire Korean citizenship, you will cancel your China citizenship. The earth is not peaceful.

You were born in a peaceful country.

I don't regret going to China in this life and being a China person in the afterlife.

If you don't understand, please keep asking questions.
