At this time, I should say yes, because from the current general trend, a standard processing time for most US applications is 6 months (except some of those applications were filed between Jan to March, that CPC really messed them up). And any further assessment required will cost time, but no one here knows for sure how long exactly it will be.
I don't know when CPC changed the rules to process all US applications at Ottawa or CPC-Mississauga, they used to process US applications at US local VOs, but not anymore, unless an interview and/or further assessment is required.
