Israeli Basic Law prohibits MKs from serving unless their foreign citizenship has been revoked under the laws of that country. Usually every election has a winner who has to renounce.

Presumably there is a procedure for non-coperative foreign governments. This must have happened before.

I've read that it's very difficult to renounce one's US citizenship....there are many oops through which you must jump. That may,or may not,be true with other countries.
