We were cleared for the ILS 30 at GYY. Our clearance was to cross HTDOG at 4;000 ft. Cleared ILS 30. After crossing HTDOG as published; the PF (Pilot Flying) PIC (Pilot in Command) entered Direct to the outer marker. ATC was assuming we were going to go to KIKVE to intercept. We went straight to the IAP WATSU to intercept. Were given a turn back towards KIKVU; but when the Controller realized he didn't have room to turn us out; then back in; he asked if we had the airport in sight; to which I responded yes; he cleared us for the visual approach. We landed without incident.
