I'm an U.S. Citizen and my sister applied for tourist visa in Kiev, Ukraine. She is married, has 16 months old daughter, has a job with decent salary, apartment, she even booked roundtrip to the US and back to Ukraine. After a very short interview in the embassy, when the officer asked her how I get to the US and she said that I had K1 visa, her visa was denied because she didn’t show her “strong ties” with Ukraine. The interviewer was rude and didn't even bother looking at the documents she had with her like my invitation letter, her apartment, salary documents, birth certificate of her daughter. My sister doesn't want to live in US she just wants to visit me no longer then for 2 weeks.
I don't understand the reasons why they denied her.
