Re: landing and moving to Québec
That's not entirely accurate, all that matters is your port of entry!
if you apply for a federal immigration, your 1st port of entry should be anything except Quebec.
if you apply for a Quebec immigration, your 1st port of entry shoud be in Quebec.
Now there is a similar process called provincial nomination, which is almost the same as a Quebec immigration but for all the other specific provinces. But you have to live & work in that particular field, in your province that has acknowledged your benefits for it.
With a federal immigration, you can move in anywhere in Canada, Try Ontario for 4 weeks & then move to Quebec, it's fairly easy!
TIP:
It's much faster & easier to apply for Quebec immigration, than for the Federal Canadian immigration.
