Hi pk,
Thank you so much for answering!
My parents are not green card holders. My dad only has an ITIN which he got when he purchased the house in the US 10 years ago. And since he no longer has any assets in the US now, I guess he only needs to report the gift tax according to Taiwan's law.
And thanks for the information about the FBAR and FATCA forms. Though I don't have foreign accounts, it's helpful information to know.
I think I'm all good now. Really appreciate the help, pk!
