N.J. Stat. § 9:7-2
Subject to the further provisions of this chapter, any agency or person as described in section 9:7-1, before obtaining the consent and approval of the Commissioner of Institutions and Agencies for bringing, sending or receiving any such child into this State, shall be required to furnish an indemnity bond, with corporate surety, in favor of the State of New Jersey in the sum of $1,000.00, to be approved by the Commissioner of Institutions and Agencies, conditioned as follows:
That such agency or person will not send or bring, or cause to be brought or sent, or receive into this State any child that is incorrigible, or one that is of unsound mind or body; but nothing herein contained shall be construed to mean that blindness in itself shall act as any barrier to the importation of any such child, subject to all other consistent provisions of this chapter; that if any such child shall, before reaching the age of 18 years, become a public charge such agency or person will, within 30 days after written notice given by the Commissioner of Institutions and Agencies, remove such child from this State; and that if any such child shall be adjudged delinquent within 3 years from the time of arrival within this State, such agency or person will remove from this State such child within 30 days thereafter upon written notice as aforesaid; and that if any such child who shall become a public charge as aforesaid, or who shall be adjudged delinquent as aforementioned, shall not be so removed from this State, then such agency or person shall at once and thereby forfeit such sum as this State, or any county or municipality thereof, shall have expended in the care or maintenance of such child; that such agency or person will make to the Commissioner of Institutions and Agencies such reports as such commissioner from time to time may require.
