I am not sure what you want to do. If you want to apply for Manitoba PNP, you need a skilled job offer. I much doubt you get hired as a plumber or a welder with a 6 month course. It is apprenticeship that takes at least 3-4 years and is also regulated in Canada which means that if you were on a work permit, having done your apprenticeship in another country, you would have to pass a test to be allowed to continue working. If you got a job offer as an apprentice, it might work. You should talk to the PNP directly about your options.
