Thanks a lot for your so much concern and help,
actually I came from another city to Islamabad only for interview after interview I got email they required this statement and the skype history I uploaded in October now they are saying they found internet option empty, now have to upload again and some more recent chat.
the problem is this they given me only seven days time to upload required documents, I made statement of my two family members today and get attested from district court of Islamabad, but record of skype history not possible unless I reached Karachi.
be happy always.
