It does raise concerns about the office with respect to particularly Sudanese refugees, and of strong concern...and your concern about so-called private sponsorships. These are often church groups and very well-respected groups in our community attempting to do that.
An example is that in 2005, a Sudanese family being sponsored by a group in Canada submitted applications to your office. The family lives in the Fugnido refugee village in Ethiopia. They fled Sudan more than 10 years ago. The visa office sent a letter saying that the normal processing time was between 24 and 36 months. They were finally interviewed in December 2008, 40 months later. In the meantime, the family had grown in size, and that meant new applications had to be filled out. Since the paperwork is complex, the sponsor had to send someone to the refugee camp to help the family. The family was accepted in principle following the interview, but they were still waiting, at the time of this report a year ago, to hear about that.
It becomes a 15-year process. With the private sponsorship willing to accept them in Canada, it seems that there isn't a contextual ability to modify your procedures to actually deal with the realities of the situation.
