Yeah
Watch me try explaining to my wife
that I have to go to court as a witness for a case of a "tourist" breaching the rules of her stay here.
I suppose they could subpoena me and make me show up, and of course my name would be in the formal court record as having "visited" the girl.
There is no way to protect yourself from this except, I suppose, to ask the WG before you get started what is her immigration status in HK? That would be a real ice breaker.
