Sorry, this wasn’t required for this visa petition, it was an unrelated situation where I needed to renew my Brazilian passport. In order to renew it, I had to prove citizenship by submitting my birth certificate but they wouldn’t take it unless that condition was removed. So I had to get the condition removed first.
Before submitting anything to the embassy, I would recommend that your fiance reaches out to the embassy to make sure that a condition like that wouldn’t cause any issues. I think it would needlessly delay the process if they deem the certificate invalid because of that condition. Best of luck!
