Hi again,
JR stands for Judicial Review. (By the way, usually threads - and forums in general for that matter - are not good enough to discuss complicated cases because, as it is often seen, there are normally pieces of the puzzle missing and people may be misadvised. However, let's continue.)
Dear, I am certain that there is something missing here, but according to you a CBSA officer never gave your husband a PRRA application and adviced him on his alternatives. And this is almost a year after his refugee claim was rejected, Correct? Also, did you file an H&C application?
It appears that, and based upon what you have so far related, because of you guys didn't take any action that may have deferred your husband's deportation after his refugee claim was rejected, he was "removal ready" at the time you filed your inland spousal sponsorship application. My advice at this point is very clear: contact a lawyer ASAP as the situation I just described may lead you guys to change the entire strategy, and things may need to be done rather quickly. If money is a concern, shop around by contacting lawyers located in small cities as their prices tend to be significantly lower than their counterparts from large metropolitan areas.
Hope this helps
S.
