Extending Open Interview at Juarez Mexico

[sym32one 2]

Hi,

My fiance and her daughter have an opened interview at Juarez until this June. My fiance has an opened custody case in Mexico for her daughter which needs to be resolved before her interview, unfortunately it will not be solved by this June.

I am trying to extend the open interview but they are not very helpful when you call Juarez. All they tell me is that I can pay the $700 Visa Fee and request more time. The problem is that they won't tell me how much more time I can request, or if I can definitely get more time, all they say is I must pay the fee first. She won't have the custody case worked out until probably September. My though was to just let it go and file another I129-F but the USCIS says that this will definitely take longer the second time around so I should just pay the fee now and deal with the embassy in Juarez.

Any ideas or has anyone dealt with anything like this?

Thanks
