Hello,
Very good question.
Just a quick note that I know of a few people who did get their K1 Fiance Visas approved based on just one visit. It all comes down to the amount of time you spend together, and the quantity and QUALITY of evidence you submit with the application, in addition to the answers to the questions asked at the interview.
Multiple visits that are short and insubstantial may have a negative effect if there’s any discrepancy in other areas, i.e. answers provided on the forms which do not match up to questions asked at the interview, prior marriages, and any indication of fraud.
In all fairness, your attorney should be able to provide you with this information as he/she would be closer to the details of your case.
I hope this helps.
With regards,
