Ill. Admin. Code tit. 56 § 250.270
An out-of-state minor wishing to procure employment in the State of Illinois must obtain an employment certificate from a City or Regional Superintendent of Schools or the State Superintendent of Education in Illinois. The requirement that the minor submit his or her application for a certificate in person may be waived by the individual issuing the employment certificate. In addition to the conditions stated in Section 12 of the Act, an out-of-state minor must also, if he or she desires employment during school vacation, obtain a letter from his or her out-of-state principal attesting to the fact that he or she is indeed on vacation and that school is not in session for the specified period of time.
