Be very careful with this. The government is looking at adopting legislation that would call into question those who've been given protected or refugee status in Canada and subsequently choose to return to their home countries for visits. I believe it's Bill C-49 and it's being debated now.
And seriously it should be too.
I have an enormous amount of empathy for genuine refugee claimants but a nil tolerance zone for those using the system to gain PR status.
PMM made me realize why there are so many claim 'fake' refugee claims, as it enables them to live and work in Canada for as long as 5 years.
