Hi, This is third time my parents about to go to b2 visa interview since past two were 214 (b) refused. They paying for their own trip expenses this is how we filing all three times.They are not currently working but got family and life in their home country. They haven't seen their 3rd Grand daughter since she was born here and she is 2 1/2 years old. Not sure what was the reason they weren't approved in past. Interview only takes minute or couple and all done so, there is really not enough to show the home ties they have. Any advice? I appreciate any help regarding this matter. Thank you.
