THE TRUTH ABOUT MONTREAL's ADMINISTRATIVE PROCESSING AND DS-5535
Just my 2 cents. I was watching this thread very closely for the last 15 months thinking that most applicants in Montreal will get DS-5535 because that's what Montreal does, but when I showed up for my Diversity Visa interview in January, I saw the real reason behind this phenomenon.
It's one word: "IRAN".
Basically, a huge chunk of immigrant visa applicants in MTL are from Iran and I would bet that most people on this thread are from Iran. Even if they naturalized in Canada or were born in Iran as Canadian citizens or even if born in Canada to Iranian parents, they all could still be subject to AP. This is something that was never mentioned in this thread and has mislead many applicants (like me) and I have come to realize that when I attended my DV interview. t all made sense and clicked. Iranian citizens are commonly thrown into AP and handed the DS-5535 sheet for a Security Advisory Opinion (SAO). This is a process that is mostly initiated by the State Department and not usually the Consular Official. Applicants are already flagged to be conducted an SAO.
The way I got to confirm this is that as a Diversity Visa winner, we are able to scan CEAC case numbers chronologically and we're able to see the consulates that interview those case numbers in question too. I know that Iranian citizens commonly conduct their IV and DV interviews at the US embassies in Abu Dhabi, Ankara, Yerevan, and the consulate in Montreal, and guess what? They all have the insanely high rate of 221g / AP that are chargeable to the Asia region which is what DV applicants from Iran are chargeable to. The CEAC data for DV applicants is publicly available where you can search by consulate as well. Here.
This is not a consulate problem. This is a citizenship problem. If you're reading this because you're anxious about getting DS-5535 in MTL and you're not Iranian or have links to Iran, don't. Odds are, you'll be fine with regards to AP if your case is clean. Now that doesn't mean that others won't be thrown into AP. AP is a tool at the consulate's hands and they utilize it for other purposes especially if they have doubts about the authenticity of the petition or if there have been criminal convictions or security concerns, but I would say that the vast majority of applicants in AP at MTL are from Iran.
