yes, the denial was under INA 214(b). Throughout the interviewing process, the consular officer failed to provide my sister the opportunity to prove the presence of the “strong ties” with Ukraine and illustrate so with supportive documentations and evidence in possession, as required in the Section 214 (b). The below is the list of factors that constitute the evidence for the presence of “strong ties” in my sister’s case:
-She is married and resides with her husband.
-She has a 16 months old daughter;
-She is to travel to the United States alone, without her toddler and husband;
-At the moment of the interview, she was in possession of a reservation for a roundtrip ticket to San Francisco- Kiev, Ukraine with dates of travel posted;
- The duration of the trip was not to be longer than 2-3 weeks
- My sister is currently employed with employment history over 8 years, and if she were to travel outside the country, her position would be kept for her until she returns. Her supervisor has provided her with a written assurance, and this document was available to the interviewing officer.
-She is in possession of property in Ukraine.
-And lastly, there is a letter from me, which further states that during the stay of my sister in the United States, I will be personally providing for her needs.
In my understanding it should be enought to show her "strong ties" with Ukraine. What else does she need to show her "strong ties"?

Thank you.
