Who knows how Americans can live in China for a long time?

If you are a man, she can legally live in China for a long time after she marries you.

If you are a woman, he can only change his nationality, which is more troublesome. First, he revoked his American citizenship, and then he applied for civil affairs in China.

I suggest you go to the street or the civil affairs department to inquire about the relevant procedures in detail. I wish you a happy foreign marriage.
