Must same-sex marriage change nationality?

There is no necessary relationship between the legality of same-sex marriage and nationality transfer, and different countries may have different regulations on this. In some countries, the legalization of same-sex marriage can provide spouses with immigration or permanent residence qualifications, but it does not require spouses to change their nationality.

If the two parties form a transnational marriage, there is generally no need to change their nationality. They should be ready to register their household registration books and identity cards, foreigners' valid passports or other valid international travel documents and proof that they have no spouse, and * * * should register their marriage at the marriage registration office where mainland residents' permanent residence is located.
