ORS § 750.311
An association or group of employers may provide health benefits in this state through a multiple employer welfare arrangement established in another state if the association or group of employers first obtains a certificate of multiple employer welfare arrangement in this state. Such a multiple employer welfare arrangement is a foreign multiple employer welfare arrangement. If the state in which the principal place of business of the multiple employer welfare arrangement is located issues certificates or licenses authorizing multiple employer welfare arrangements to transact insurance or provide health benefits, the foreign multiple employer welfare arrangement must show in its application that it is authorized to transact insurance or provide health benefits in that state.
