I see a couple of possibilities:

1) Who is closest (relationship-wise) to this guest? Doesn't sound
like you're the one inviting him over. Have that person say a few
words, tactfully and privately. I don't think it is your place to say
anything - unless you are very good friends already.

2) Have someone (much) older say something - again, tactfully and
privately - to the guest. It may go down a little easier in that
context.

You know this could fall out a few ways. The person could be
shocked/horrified/embarrassed to find out that he has bad table
manners. He may laugh and not care (and not change). Also, keep in
mind that it is harder to break habits as an adult. He may be angry or
irritated - or worse yet, be a grudge-holder, long term resentful, etc.
So tread carefully, since it seems you will have a long relationship
together.

I used to work with someone (from a different country) who chewed
loudly and spoke with his mouth full. He was older than me, higher
ranked job-wise, and a super-nice, really smart and generous guy. I
never said a word about it, just tried to sit at the far end of the
table (we usually ate in groups). Sometimes my sister will talk with
her mouth full, and I will tell her as kindly as possible that I am
happy to wait to hear her news until she has finished her bite of food.
She forgets that she is doing it and always seems to appreciate the
reminder. Ditto for one of my friends who tends to eat while we are on
the phone together.

Let us know how it turns out!
