oh k... It seems that your sister has sponsored her husband.... please correct me if I am wrong....
I knew that the process is delayed from last 2 months due to higher volume of student visa applications at all CHC across the world.... However, after 2nd week of August most of the embassies are done with student visa processing so, we can expect some good news from 3rd week of August onwards..... We might hear some great news this week too if we are little more lucky....
So, my fellow thread members, don't loose your hopes. Its just matter of another 1 or 2 weeks. We are almost there. Let's hope for the best for this week.
All the best and Cheers! ;D
