If you really want to be a doctor, don’t come to the US.
Go somewhere you can begin your medical studies right away, without losing 4 years (and spending more than $150,000) on American-style pre-med education given how very, very few international students are accepted to American medical schools. The odds are staggeringly against you.
As for medical school, count on $250,000+ There is little to no financial aid for international students even if you’re among the few international students who get in. Many medical schools demand that your parents prove they have the money, and some demand your parents deposit this entire amount in a special account before you can attend.
