N.J. Stat. § 34:15-55.1
Any employer, not a resident of this State, or any employer not licensed to do business in this State, or any resident employer who becomes a nonresident of this State after the occurrence of an injury to an employee, who shall employ or who shall have employed any person to perform work, labor or services within this State shall be deemed by the accepting of the privilege of engaging in such work, labor and services by his or its employees to make, constitute and appoint the secretary of the workmen's compensation bureau as his or its agent for the acceptance of process in any proceeding by any such employee or dependent or representative of such employee, under and by virtue of this chapter; and the acceptance of such privilege or the entering into this State for the purpose of engaging in such employment shall be a signification of such employer that any such process issued against him or it, which is so served, shall be of the same legal force and validity as if served upon him or it personally.
Service of such process shall be made by leaving a copy of the petition with the secretary of the bureau, or some one designated by him in his office, and such service shall be sufficient service upon such nonresident employer; provided, that notice of such service and a copy of the petition are forthwith sent by registered mail to the respondent to the address stated in such petition, by the secretary of the bureau, or such person acting for him in his office, and the respondent's return receipt and the affidavit of the secretary of the bureau, or such person in his office acting for him, of the compliance therewith are appended to such petition and filed in the office of the secretary of the bureau wherein such action may be pending; provided, also, that the date of the mailing and the date of the receipt of the return card aforesaid are properly indorsed on such petition and signed by the secretary of the bureau, or some one acting for him.
The workmen's compensation bureau in which such action is pending may order such continuance as may be necessary to afford the respondent a reasonable opportunity to defend the action. The secretary of the bureau shall keep a record of all such processes which shall show the day and hour of such service.
This section shall be construed to extend the right of service of process upon nonresidents and shall not be construed as limiting any provisions for the service of process now or hereafter existing.
