First off---why are you posting this here? May get better feedback posting elsewhere.

In general you cant if you are a not a resident.

the rules are at the state level so each state has their own rules. for a state to issue a license a person needs to have some sort of residency in the state.

Some states have a special set of rules for Canadians than they do for other counties. Many retired Canadians split residence between Canada and someplace in the southern states (California, Florida, or Arizona) in winter.
