I had another look at DV-2014. The table shows the outcome on the left and the quotas according to the law. I referenced all numbers to EU region resulting in a global quota target of 53,721 visas -- not 53,900 as I remembered
.
EU, AS and SA are perfectly aligned, OC seems a little short while AF region is a complete miss.
So can quota considerations slow down Europe? Well I guess yes. Reading the law there is a lot of talk about quotas and even in the event that a region's selectees pool gets exhausted early the talk is about quota and never about numbers of issued visas -- apart from the 55k cap (and NACARA). So it seems to me perfectly legit to issue only 49,000 visas but having the quotas set right. Therefore I consider May and July as necessary one-off corrections to the (relative) quotas to get the regions better lined up before year's closing.
I was happy to see that the Visa Office have learnt their lesson from DV-2014 and are reacting early on AF's lag. Looking now at the May 15 extract and seeing (again) only 800 visas issued to AF region makes me feel less optimistic. So far no one at the VO seems to be aware of the no show issue. The hilariously low number of selectees in DV-2016 is striking proof of this. EU region has nothing to fear from backlog cases, they were starting to level off a month ago (yet to be confirmed this month) and DV-2015 could be a wonderful year for Europe -- even for high case numbers. My only concern is the poor performance in AF region. I still hope for a hefty increase of the AF cut-off in August (and September).
