Hi there,
My fiancé had his K1 visa interview last Thursday, and the officer asked basic questions. Then, she said, 'Congratulations, your visa is approved, handed him a paper with instructions on how to collect his passport, and said he should receive it in 3-5 days. The status changed to 'refused' on Tuesday, and they contacted us on Wednesday, stating that the case is in ongoing administrative processing, and requested copies of his old passports -he holds two citizenships-, which he had not used since 2011. So we did, now I am concerned about why they asked for that, and how long does this usually take?
Note: the officer asked to see the requested passport in the interview, so he told her it had expired, but here u go. She saw it and gave it back.
