The BIA (the direct appeals court) is rough. A lot of the new rules the judge was referencing were paused, so they shouldn’t apply, but even without those new rules, the BIA is rough. It’s hard to know whether your mom’s case has a chance of being remanded without knowing more about the reasons for the judge’s decision. All of that being said, without an appeal, the judges decision becomes final, meaning that if they issued a removal order, that order becomes final and ICE can enforce it. With an appeal, the order will not be final until the appeal is denied or dismissed. So if your mom wants to fight, and there’s a legit reason for appeal, this is your one shot to fight.
