Hi jdCanadian,
I know you didn't direct your question to me but, for purposes of the police clearance certificates validity dates for Express Entry, "short visit" and "stay" mean the same things. People assume that, because they weren't 'living' there, they were just 'visiting', it doesn't count, but it does. The point is that, if you go back to a country even for 1 hour after you get the PCC, the results of your PCC aren't complete (because they don't cover that 1 hour) - you could have committed a crime in that 1 hour of visiting, and the PCC wouldn't reveal it, so it's not valid.
Therefore (unless you're currently living in that Country, in which case the rule is that the PCC just needs to be less than 6 months old), if you went back to a country for a short visit after the PCC was issued, it's invalid and you may have issues with your application if IRCC realizes this.
There are some people on this forum, though, who state that, if you already submitted your eAPR and received AOR, then it is fine, as IRCC wouldn't expect you to now either stop travelling until your PR is approved, or get a new PCC after submitting your application...I don't know how true this is though...
