I am very sorry for your situation. Nobody should be forced through such dilemmas. I do understand his attachment and duties and obligations that he has as a child to his parents. But he’s not only a child anymore - he is about to become a father and has to realize that. It’s though, heartbreaking and soul crushing, but putting his own family into legal and financial instability to say proper goodbyes to his passing parent sounds like a very reckless decision with long-term complications. Sacrificing his soon-to-be child well being does not sound like a fair deal.
