I want to study in Canada and later want to immigrate to be a dental technician
Studying dentistry is difficult in China, some require you to be a citizen or have a green card before you study, so you need to apply for a green card first now
Studying dentistry is expensive, prepare at least 200,000 dollars. Long time, 5-8 years. Difficulty, if you can't get 8 in English IELTS and 110 in TOEFL, it may be hard to graduate from dentistry.
