Seeking my fortune...

They said, during the the BUNAC orientation, that one of the few restrictions on our work permits is that we can't freelance. I'm going to ask about this on Monday morning, but I'm assuming that means that I cannot (for example) write an essay about living abroad, I could not legally sell it to a newspaper or magazine here. I'm quite curious as to whether or not it means I could not write something and submit it to an American publication. One wonders.
