as far as inviting a goy for yom tov meal, wolf is that heter your own, you didn’t see it in a sefer, or did you ask someone?
Yes, I discussed it with someone.
Again, there is no issur, whatsoever, to invite a non-Jew for a Yom Tov meal. If, for example, I were serving nothing more than deli sandwiches, there would be no issue whatsoever. The issue is only in the cooking for them. You simply cannot cook explicitly for them.
In any event, don’t rely on me for a p’sak. By all means, CYLOR.
