GV applications of Polygamous/Polyandrous marriages

Hi Everyone
Just wondering how Polygamous (most Arab countries) marriages and Polyandrous (South Africa) marriage set ups are handled in GV applications. Is there anyone here with knowledge and/or experience in this?

Regarding polygamy and Portugal’s GV, a few lawyers weigh in. I imagine the same applies to polyandry. What does the Portuguese golden visa law say about providing permanent residency for investors with two wives? - Uglobal
