I'm thinking about filing a I-824 later this month or in early July, if we remain in Administrative Processing at NVC for more than 5 or 6 weeks.
Has anyone used this successfully to activate an approved I-130?
NVC says all cases are considered separately. If the problem is, in fact, a request for a second K visa, then maybe processing for a CR1 won't get caught up in security checks. Her AP at NVC for her K1 two years ago was over so fast that we didn't notice it.
