Hey - I did a little more poking around. If it's for less than 180 days, the world won't end. Better to not involve your friend as a middle man at all. For 180 days to a year's worth of going out of status, she can be banned up to 3 years. But for over a year's worth of work/being out of status, that's the 10 year ban.
However... none of it is recommended, and if it were anyone I were responsible for, I'd smack them silly just for thinking about it.
