Yeah in Ukraine there are no such red books or anything. The marriage certificate is all you need to be legally married there.That might be the key. That registration man. In China they have these stupid.red books which ircc doesnt accept. Tje day we married.instantly after we went to the bureau in her home city and registered. It was a notarized in front of us. In English and Chinese. All info included, dob, pp number, pp info. Thats what foreigners need in China to.prove marriage and what IRCC said they wanted from.me in country specifics.
