I guess it doesn't need to be said, but, Can i get punishment if i drive while my license is expired?
Of course you will. Not only penalties but fines too. For example, you could pay a fine that range from $25 to $40, and you have to keep in mind that amount can be bigger.
Can i change my address and even so, i'll be able to receive my documentation?
You can indeed change your address, but we cannot guarantee that you'll receive your documents on your new address.
