To which rule are you alluding? The two year home residency rule does not apply to all J1 visas, and even where it does apply it does not prevent the person subject to the two year HRR from obtaining a non-immigrant visa, so it won't prevent issuance of another J1. The 12- and 24-month bars for eligibility for future J1 status apply only to persons beginning an Exchange Visitor program in the categories of Research Scholar or Professor.
