Please, how can I start the process of migrating to Canada for Postgraduate studies and subsequently for a permanent job? I am a degree holder with Postgraduate Diploma. I am 41 years old father of four children. I have over fifteen years of work experience in a government-paid job in Nigeria. Must I have TEF, TCF, CELPIP, or IELTS score to start the process? Though, I have skilled work experience.
