How long will it take for China people to get an Italian visa after they marry an Italian in China?

First of all, you need to register with the domestic civil affairs bureau to get the license. (1 working day)

Secondly, the marriage certificate needs to be notarized by a domestic notary office (Ministry of Foreign Affairs certification+Italian Embassy certification) (about 15 working days).

Thirdly, the Italian side needs to go abroad for family reunion and prepare various materials.

During this period, China can apply for a visit visa.

The whole process takes about half a year.

I hope I can help you.
