What job do you want and how do you go about getting that job?

I was asked, "What job do you want and what do you need to do to get that job?" Here's my answer. ^^ Could you correct what I'm saying and make it sound more natural?

I'd like to work as a nurse in Canada since I have working experience as a nurse in an intensive care unit in my country, so I'd like to keep my career. To become a nurse in Canada, first, I need to pass an English exam. After that, all of my Korean nursing documents such as my nursing diploma, transcripts, Korean nursing license, and career certificate need to be examined and authenticated. Also, I need to take several exams such as the Canadian nursing license exam and other types of general knowledge and practical exams. Then, the nursing association will let me know if I need to take additional theory classes or practicum(?). I think it will be a really long journey.

Overall this is really good. I don't know what you mean by theory classes or practicum but other than that this is totally coherent and comprehensible so good job. The way I corrected this isn't in formal British English but I tried to make it sound like what I'm used to hearing--informal, American English. Anyway, good job and keep up the good work.
