My Canadian company wants to keep me on when I move to the US. I realize the drawbacks to this are CAD/USD conversion and lack of health insurance. However, no gap in employment would be helpful. So I have a few questions that I haven't found clear answers on in the search function:
1. Do I need to switch to contract instead of permanent salaried after I have my PR so that I'm not paying Canadian taxes via pay deductions?
2. If I activate the PR at the border and then return here for a few more months to tie loose ends, am I officially beholden to the IRS for work done in Canada from that day forward?
3. Will I end up paying overlapping taxes in both countries for those few months I live in Canada with a green card?
4. Is there any period of time between the C/IR-1 activation and receiving a SSN that I cannot work? Or is there something like registering a tax number that would allow me to continue working while in Canada?
