Moving from Canada to Florida

We moved from Ontario to Florida, currently we are considered tourists and are in the process of acquiring a visa, we have an address of residence would like to get ourselves a Florida Driver's License (to use as State ID)

Question number one: is it possible to acquire a Florida driver license without a US visa

Question number two: if it is possible, will a G2 canadian license be converted into a full Florida license, or a g2 equivalent if there is one?
