Welcome aboard newbies. It's always good to extend the forum family so we all can get better processing ideas.
@ Keep the faith, WOW, that was quite some detail and I thank you for sharing it with you. My story is somewhat similar except that I was never detained but I was a refugee and everything failed for me, hence, my being deported. So, has your hubby's ARC been approved? I think it takes them about 6 weeks alone to process the landing fee and ARC can take anywhere between 2-6 weeks as well. Is his medical up to date in his file? You have to take all these little factors into consideration. If you had your interview in August and I am assuming you paid your landing fee, it would have taken the VO somewhere into mid September. Then there is the ARC which apparently is a pain in the arse for them to do according to my VO at my interview. So that alone would add an additional month or two to the processing. I think you are somewhat still within normal processing according to POS. Oh, I forgot to mention background checks. That can take a little time and seeing that your hubby was detained in Canada they may very well want to dig a bit deeper to make certain he is not a criminal of any sort.
In terms of getting correspondence from the office, it really depends on your IO. Sometimes they contact you via email that is on your file or they send a letter out. I believe my IO does it the old school way in which he sends out a letter. Still I am waiting to get something in the mail because my next Bring Forward Date on my file is ending of this month. Also, I am waiting on them to send my ARC request to pay my darn 400 bucks. I think I may have to cancel out the holidays and very well look into January.
@ Star apple, my only best advice to you is to sit patiently and wait hoping that each day will bring some news. POS is by far the lamest office ever when it comes to this immigration hoopla.
