What does it mean to re-open immigration case?

Question

When my father died they closed the case for my mother. But before he died she had received the approval letter. So this has been a roller coaster. She has been going to appointments every few months. What can she expect now that they re opened the case and that she has the approval letter? Anything good in the future for her?

Answer 1

well that means they're gonna analyze this case an maybe there is something good coming.
