on its own, no, your Brazilian license is not valid.
If you obtain an International Driver's Permit and use that in conjunction with your Brazilian license, you are allowed to drive in all US states.
If you are stopped by police, you will have to produce both documents. The IDP is only valid if your license from your home country is valid - and only for the same class of vehicle (ie no motorcycle license at home = no motorcycle riding in a foreign country).
The IDP is not valid in the country of issue, so get one before you leave Brazil. Your state roads department will be able to help. the IDP costs about $US15. almost 9 years ago
