How to make State not required based on the Country selected?

[Yolanda]

Questions:
When a user begins to fill out payment information and switches to a different country that doesn't have states, we are finding that the state field is still required. How do we make the state field required if the user is in the USA, but optional if the user is in another country?

Answer:
I'm afraid that the mandatory setting for State field is working as all or nothing, which means if you set it to true, then it will require State for all countries, and if you set it to false, then it will not require State value for any country.
