Where are you going to school? E.g. Canadian med schools almost never accept any foreign students as they cannot remain to work there, so why waste space when there are not enough spaces for all the qualified Canadians who want to become doctors? US? Very few US med schools accept any foreign students, and those where you can apply expect you to prove you & your parents have sufficient funds for all your school + living expenses for all 4 years - currently USD500,000 & up.
Medicine is not worth the time & money unless you are totally committed to healing, and will work in your country of citizenship. You don't go into medicine for the money & expect to be successful. It's too hard, too expensive, and takes way too long.
