am a graduate of building technology from a university in nigeria west africa. Though i hold a bsc i want to do something with my hands. I have a passion for water as long as it has to do with water. So i want to learn a trade in plumbing or water engineering and i would want to do this abroad canada, australia or any other country with good working environment. How does a foreigner get apprenticeship in this countries, what needs to be done, how much can one make and any other information would be very helpful.
