It’s definitely possible, given Yazan’s past history with the show, that he could get another season, but it would have to happen on a spinoff like Happily Ever After? or another series where the K1 visa process isn’t a key to the story.
The engagement (assuming that’s accurate) is interesting because one would think it opens up a door for Yazan Abo Horira to appear on 90 Day Fiancé once again with his new girlfriend.
Still, with her being a Jordanian citizen, one has to question how willingly the franchise would cover a couple who has no ties to America.
