Think there is already a post on this topic....
Anyway, I don't know how easy it will be for persons in regulated professions like Nursing. Apart from the degree/diploma assessment from WES/ ICAS, you would still need to go through NNAS and then apply to the provinces should you intend to practice Nursing in Canada. Even if you don't, to get a job offer or a provincial nomination you have to be eligible for registration with the province. To do this, you need to register with NNAS... Takes quite a while...
See the following statements....
I think its very difficult to get a job offer....
If the employer wants to "save" $1000 then immigration is not going to look into your job offer as valid, remember, per immigration regulation a potential employer has to provide evidence that it has tried everything possible to hire a Canadian resident/citizen before approve the employment offer to you... This is the purpose of a LMIA.....
