No tata there has been no such motion to "remove" citizenship from those whose parents were/are illegal, as a matter fo fact there is not even a real way to confirm this one way or another in most cases. the debate is whether to not allow US citizenship in the future in such cases.

I also concur regarding Malaysia. Unless specifically allowed by the Malaysian government, and I believe there are less than 20 cases, Malaysians cannot hold dual citizenship, it has been this way since Malaysia's founding.
