So here’s what I understood:
spouse 1 was a DV winner. He was a beneficiary.
Guy got arrested for DV, then she went to SA and got divorced. He moved after this, several times. But because someone told her they needed to divorce in the USA, she did it, so now she’s got two divorce decrees: one from SA and another one from the US.
In between all of this, he applied for a spousal visa for spouse number 2, whom she knew even before he married spouse number 1. Both him and spouse 2 are from Congo.
Marriage with spouse 2 is invalid because apparently the decree from SA isn’t valid. So if he got married to number 2 while still married to 1, marriage 2 is invalid.
Aaaaand he was apparently surprised that the officer spent an hour looking at addresses, and that he didn’t get the approval yet.
Am I missing something?
