This isn't good. So someone living here legally and obeying all the immigraiton laws will be denied a drivers liscence? Students, H1B holders, company international transfers and investment executives won't be allowed to drive in Michigan? Someone turn out the lights when the state finally goes the way of Detroit.
If their home country is a signatory to the international driving treaty, they can go to AAA and get an international driver's permit which is valid as long as the license from their home country is valid.
Anyone with brains need only look at the passport of the foreign visitor to determine if they have a valid U.S. visa stamp or not. Possibly those type of people are in short supply in Michigan's DMV.
To my understanding, those folks you are concerned about are able to obtain an ‘International’ license which is valid in the U.S...
I don’t know the details...Maybe someone else does...
