Just remember…even IF your son graduates from a college on Michigan, that does not guarantee him admission to medical school…in Michigan or anywhere else.
Think of the other things you will also need if you move to the states…first up would be health insurance.
You would,have the advantage if your son being able to attend either University of Michigan or Michigan State…or any of the other Michigan publication at instate costs should he be accepted there.
In addition, there are several public medical schools in Michigan which would be less costly for him as a resident IF he gets accepted.
