I would decline this request.
I read your posts on the other place you posted this thread and read the additional info. Such as that this man spent 11 years in the US and has most recently been living in Saudi Arabia.
Neither the USA nor Saudia Arabia are nations that typically have residents seeking asylum. So for that reason his claim of seeking asylum from Saudia Arabia seems dubious and red flaggy. Of course there are always unique circumstances a person can be in -- but when screening an inquiry, we cannot possibly know everything involved, and thus need to make decisions based on what is apparent just in the inquiry itself, or what are able to ask about, and need to consider red flags.
Secondly, a person truly seeking asylum in your nation is likely to have an entirely different emotional situation than one coming to your nation for a vacation -- wouldn't you think? THey might be experiencing trauma, emotional suffering, painful things. There might be some "drama." As opposed to the light and joyful demeanor we more commonly associate with someone on vacation. So it is good for you to think of what kind of emotional atmosphere you want in your house. Because I am particularly sensitive to the mood of guests, and a heavy mood can negatively effect me, I would not want any kind of emotional heaviness or "drama" brought into my home by guests. I am clear that I'm not running a charity organization, or offering therapy services to guests, though some hosts like to do that.
ANother red flag, for some hosts, is simply taking a person who wants to move to their area, since someone seeking long term housing might decide that , whether you are willing or not, your home makes good long term housing for them. Of course not every person moving to an area is going to become a squatter, but that is a risk with this type of guest, that you will not have with a guest who is not planning to move to your area. As well, guests who are moving to an area and whose ultimate goal is to find long term housing in your area, can behave differently in your home than guests who are only visiting the area on vacation or a work trip or such.
So I would decline.
