Hi all, just wanted to update. Brief recap: my husband interviewed in Montreal on April 27 and was given 221g and sent a DS5535 the same day to which we returned promptly. His case received several updates early then an update in mid July. Other than that we have heard nothing else from the consulate.
I reached out to the US senator's office from my state and requested they contact the consulte for any information and possible expenditure to which they promptly did and received a lengthy response from the consulate the same day. The main part of their response is as follows:
"Unfortunately, due to the national security nature the U.S. visa process, the Department of State will not disclose why a case has been placed into administrative processing, and issues can often vary greatly with regard to complexity. For example, the consular official may simply need to verify additional biographical information. However, it could be much more complicated like verifying previous travel itineraries or needing a foreign country to provide criminal records, etc. That being said, there may be no issues with his application, but it may have been flagged for an internal quality control review or audit.
Most administrative processing holds can be resolved very quickly, but some take a substantially longer time. During this period, no congressional office can request expedited review or appear to influence the outcome of the application."
The two big and disappointing takeaways from this are that you may be placed into AP and your life put on hold for absolutely no reason other than "quality control" and that no one may intervene on your behalf. I found the quality control statement particularly interesting as I've never seen that mentioned as a reason on any forums I've read in regards to this process. Anyway just wanted to share and good luck to everyone out there stuck in limbo.
