I think you will find that people who immigrate here and live here as permanent residents or become citizens are more than welcome by coworkers. This is a country built on immigration from centuries past. But don't expect a welcome mat if you are just looking for a temp workers visa or something along those lines.
I think you are setting yourself up for failure if you have an idea to get a 705 airline job at any airline in this country as a low timer just starting out. As a low timer you should expect air taxi or commuter options maybe getting a start as a Beech or Metro F/O if you're lucky.
Cargo airlines here such as Kelowna Flightcraft (Purolator) hire pretty high time guys as well to ride sideways in the 27s or DC10s - even the Caravan guys at Morningstar have ATPLs, several thousand hours and did a few years in the back of the 27 before they were able to get that spot...
Good luck coming here but know that you will not get a job without residency first and then you will work your ass off to compete with 100's of guys trying to get the handful of jobs that will take guys getting their first start.
