Congratulations. It made me not lose hope. I have the same NOC as your wife but no ties with Alberta. I currently work in Canada under NOC C but not in Alberta though. I just received the application package this morning together with the checklist. Getting all the documents ready now for submission. Thanks for this forum.
Just a piece of advise!
Working in a different Pronvince other than Alberta may be an issue and not necessarrily an advantage.
so what do you do?
in my Wife's case, i have a brother in Nova-scotia, which can be deem as a tie to Nova scotia and not to Alberta.
We included a LOE- letter of explanation immediately after the application form.
we made research and highlighted reasons why we prefer Alberta to any other province
we gave reasons while, though having an in-law in Nova-scotia, we do not have any intention to reside in Nova-scotia.
I advise you to do so too.
Good luck to you.
