Limited service is available on weekends: please call on a weekday to obtain hours of operation.
A request for CBP clearance must be made in advance by speaking with the Duty Officer. An APIS transmission or voicemail will not suffice. If services for general aviation are required after regular business hours, listed above, call by 4pm on the preceding business day to make arrangements for services. For emergencies only, pilots should contact the Communication Operations Branch at 1-800-973-2867 and ask to be connected to the Customs and Border Protection (CBP) Duty Officer at the Port of Rockford.
The officer is responsible for many duties which take him/her away from the office. It is advisable to call in advance to insure that the officer will be available.
