People keep repeating that he broke a law and was planning to work for pay, the pay being a single meal offered by his host at one of the coffee houses he was going to play some songs at.
I have not seen any evidence though that someone giving you one dinner during a trip qualifies as pay in exchange for work.
It seems to me that it is a fairly common occurrence that one is treated to a meal by a friend or associate while traveling.
Does anyone have actual references to law that make clear that being treated to dinner qualifies as being paid for work and thus triggers a visa violation and reasonable cause for deportation?
