Marriage or stable union?

Hey Guys, I have been thinking of getting a stable union or possibly marrying my girlfriend here in Brazil. I have my BC and I need my Certificate of no Impediment. However, I am not sure on how to get the certificate while living here in Brazil.  Any suggestions would be much appreciated! Thank you in advance! -Anton

Hello! How are You? Well there is literally two options you either go to your country of origin to retrieve  it or you can get it through  the embassy  or consulate.
