Practice under this rule shall be limited to the above causes. The permission granted by this rule shall become effective upon filing with the clerk of this court for Suffolk County a certificate of any such court of another jurisdiction certifying that the attorney is a member in good standing at the bar of that court, and also (a) a statement signed by a representative of the law school that the attorney is enrolled in the specified graduate program or (b) a statement signed by a representative of the organized legal services program that the attorney is currently associated with such program. An attorney engaging in practice under this rule shall be subject to the provisions of Chapter Four of these rules, and the permission granted by this rule shall be conditioned on compliance by the attorney with the requirements of rules 4:02 and 4:03.
(2) Practice under this rule shall cease whenever that attorney ceases to be enrolled in or associated with such a program. When an attorney ceases to be so enrolled or associated, a statement to that effect shall be filed with the clerk of this court for Suffolk County by a representative of the law school or legal services program. In no event shall an attorney engage in practice under this rule for more than two years.
