Is it possible to do an apprenticeship on a student visa and then move here on a skills visa? I've read online that foreigners can do a 2 year trade course here but I'm not sure if that counts towards the experience you need to get the skilled visa. I'm british, 28, male. Currently on a WHV. I have 10 years of experience in plastic/GRP fabrication and pipe fitting. I dont have qualifications. Im skilled and learn manual jobs quickly. Ive seen that there are some courses that allow you to become qualified in a trade in 2 years. Im bored of fabrication but id like to become a plumber as my skills are easily transferable and its very similar to my last job. It also pays better. I apreciate any help or advice you can give me. Its hard to know how to go about it unless I pay somebody a lot of money. Thanks
