Can a Canadian LPN work in the USA as a travel nurse? Or do you have to be an RN?

I would like to work in the states as an LPN and so far I have only found information for RN's wanting to work in the USA. I would like to do it as an assignment with a travel nurse company. Any suggestions or websites would be greatly appreciated.
