Its a good sign, that CIC responded ..... Go thorough yr case, prepare yrself for concise or to the point answers........ I think they only concern about yr location (Kabul, Afghanistan), but if yr all docs and case is genuine, so don't be afraid.......be confident to face CIC representative, it may be a formality to meet u only............ but u must present for an interview as they called for, unfortunately,no other options !!! ........... Best of Luck, Dear Kashif .......... this may be yr last CIC Viva (Inshallah) .... Light tunnel is just ahead....... Good Luck.
