NOA 2 expiration date

[VolimTe 0]

Hi everybody,

We recently received our noA2 and it expires in February

I am having a problem with my fiancé's papers, my soon to be mother- in law's last name is spelled wrong in the place where she got married and thats where my fiance was born. my fiance went to gather some documents for the visa such as police certificate etc, unfortunately they told him that her last name is wrong and he has to go alllllllll the way to Croatia from Bosnia to get his mom's new birth certificate because the one she has is older than 6 months... i am scared that my NOA2 will expire.. what do i do i know its in February but and that is 2 months away from now but just in case if something goes wrong what do i do about that i know the embassy can extend the NOA2 date due to their mistake.. :/ but .. this is not their mistake.. anyone with the same experience that had to extend NOA2 date due to the problems with the documents
