Hi,
I landed in Canada successfully on Apr 4th. I had to return to the US to finish some stuff before taking a vacation and the experience was unforgettable. At the US border office I was quizzed (more like beat up)for about a half hour. The US officer in charge made a copy of my Canadian Landing paper and said that I can't have residency in 2 countries. He said that he was going to stop my residency process in the US, in spite of the fact that I have not even started the US green card process (Labor certification pending) and had applied for Canadian PR atleast a year before my employer applied for my labor cert (changed employers). I thought that he would refuse entry to the US, but luckily after a lot of pleading that I need to finish things up in US, he gave me entry.
So all of you guys/girls on 485 and AOS pending, beware, these are not good times to land in Canada with a PR. Heck, I've not even started my green card process, yet the guy gave me so much of angst and made the 1/2 hr a living hell for me. This is after I've lived 9 years in the US as a law abiding and tax paying person.
