I don't know what to think anymore. My sister is a Polish National. She currently lives in England. She tried for the visa 2 times(last year and this year). We had all the supporting evidence and every single document. All she wanted to do is visit us for my sons graduation. The agent denied seeing her evidence and denied her visa right away. She is 30 years old.
P.S. My mother overstayed her visa 6 years ago. I was married on a B2 visa and currently with my husband for 15 years. Was this the cause of the immediate denial?
