Will an accidental overstay of a tourist visa affect our K1 approval chances? We got approved by USCIS in November and waiting for NVC to receive it. My fiancee was staying with me here for the past 3 months on a tourist visa, which ended on December 28 and his flight home was booked for that day. Unfortunately his international flight got delayed and didn’t take off until 1:30 am on December 29. Could this affect our visa?
