My sister married USC, their interview for i485 and i130 was postponed twice because 1st... the notice was lost in the mail and it came 2 days before so they called to cancel it. It was re-scheduled on Dec. 16 but they canceled it again because my sister has a flu. Also, they are having marital problem and the husband is not cooperating. They might end up in divorce soon. She was already issued a work permit. What will be the possible scenario?
