The prevailing opinion on this seems to be that if a guest receives mail at your home, they can use that to establish residency there. This could end up being problematic; so, doing some legal research might be in your best interest. Also, around long term convenience, once the mail starts it is not always easy to stop it. You could be getting their mail, and junk mail, for long term at your address. This is a good question and you should weigh your options after doing some research. There are mailbox storefronts just about everywhere, which could provide an alternative, and they would likely know the legal ins and outs of the service they provide.
