My dad has won DV2011. My mum was also joint applicant with my Dad. We already got the 2nd letter also. The fact is that, i did a little mistake when i was submitting the DV application. The mistake was that, my mum's actual name is MAMTAZ but i wrote MOMTAZ there by mistake. My mum's all certificates are with her Actual name which is MAMTAZ. Now, what should i do ?? Should i have to change all her certificates ?? They called them for interview on February 2011. Time is so short. What should i do? Plz tell. Another question? Will they have to show national ID card ??
