You are therefore advised at all times to dress, behave and live decently in hotels as becoming a bona fide tourist.

Your Visit Pass will be cancelled and you will be ordered to leave Malaysia within 24 hours failing which you will be prosecuted under the Immigration laws.
Furthermore you will not be permitted to enter Malaysia again.
