Nour140,
U can try going for interviews if u happen to be in calgary for visit but i would advise u to send in yr resumes way before u enter and try to set up appointments for interview while u r in calgary. However, if u are not a PR, the chances of landing such jobs may be a problem unless the companies are deseperately in need of people like u. It actually depends on the company's needs and willingness to sponsor u to work in canada. Furthermore, yr qualication also needs to be assessed according to the canadian standard for the companies to recognise yr credientals, so u have to get it assessed for the companies to recognise yr qualificatons. As an engineering degree holder, yr degree also needs to be accreditated by the engineering board of canada to be able to be recognised by the employers, especially those in yr specialised field. So u still need to get yr qualification assessed before u can procced to have yr qualifications recognised in canada.
