For everyone saying that Nicole's mother should just take Mae away, remember that in most states, grandparents cannot even get visitation orders very easily if the child's parent doesn't want them to. And the process of finding a parent incompetent is very complicated and strict (for good reason - it *shouldn't* be easy to take a child from a parent b/c as you can imagine, or see on our southern borders right now, the damage of family separation is very real). Without clear evidence of child abuse or severe neglect, if I were Nicole's parent's attorney, I would tell them it was absolutely in their best interest to stay in Nicole's life as much as possible. If I remember correctly, that is even the reasoning her father gave for giving her money and sponsoring Azan's application; that he'd rather have her, and Mae, here in the states and not in Morrocco. But, without more, a court is unlikely to find moving abroad alone sufficient reason to take a child away, unless there was a second parent objecting.
I don't know the details of custody rules in Nicole's state (I also don't at the present moment remember what state that is - Florida?) but it is absolutely not a slam dunk that Grandma and Grandpa there could get custody even if they wanted to. Their best bet would be, frankly, bribing her to get her to leave Mae home and/or send Mae home after the wedding. Perhaps that's why Mom bought the dress and it sounds like all of the parents are heading over for the "wedding" that I'm sure they're paying for.
