thanks,
I ve checked the e case and its ok with the file number which I recived before and the one mentioned in my Medical request,
but when I recieved an e mail from PVO regarding documents for my baby they used the below as file number
[size=10pt]FILE N° VF / B------------ - B--------------[/size]
first one is the correct one and the second I dont know from where it comes ( may be its my old file number I need to check that )
but in general does visa offices send file number like the above format ( two numbers ) and is it like sub file for my baby or my wife?
