I am in USA (2nd generation Indian American, if that is relevant) and have witnessed situations where person A let person B (A's wife's distant relative) stay in their apartment, but they overstayed their welcome.
In a particular situation (20 years ago), person A gave person B a newspaper "roommate" section to start looking for new place to live (I'm sure there are more details, but this is all I know).
The laws in USA (or at least my state) are that, if person stays in your house for 30 days or more, that person is considered a resident (i.e. staying for free, not helping with household work, etc), and cannot be evicted.
My question, how do I politely refuse anyone to stay at my home.
I really want to help people in need, but human nature is thus, and I have a history of porous personal borders. (this site on Stack Exchange is a real God-send!)
For example, should I respond with, "I am currently not looking for boarders" while maintaining current, reasonably favorable relationship.
This may apply to acquaintances, but how to apply this to relatives or better yet, Family Doctor who has practice in our building and knows everyone's weakness (because that is how US Doctors are trained).
Hopefully the situation will never arise, but I wish to learn beforehand.
