Been there done that, not with a lawyer but with tenets who know how to play the system.They are called professional renters, and that's what he's doing, He's going to stay there as long as possible with out paying rent and is putting the money in his pocket at your expense and doesn't give a rats "BEEP" if you lose the house or end up in the street.He has declared war on you, your family,your money and your life, Get a bull dog of a lawyer who take pride in the profession, go after eviction,judgment for all back rent,late fees,court costs,filing fees anything you can attach.

I never take anything with me to leave in the states, I never work on the property (though I can), I always have my passport out and I am polite to the officer (never hurts to be nice).Coming back, I either have nothing to declare or am well below the limits.
