CAA Website and Annex A to CAP 804 suggest that "Counter Service" is available for addition of IR to an Existing EASA Licence. Form SRG 1161 AND ALL the supporting documents must be in order or its a no-go. If your medical records are in the UK and you have a non-expiring ELP endorsement on your existing licence JAR CPL and the examiner has self briefed and the IR test was "approved" and all the other bits are in order it should be OK. You state you are living in Turkey? If you hold a JAR CPL with a JAR medical issued in Turkey, even if the medical is still current, you will need an EASA Part Med before your Part FCL Licence is issued. Check out CAA Website and SRG 1161, And Annex A CAP 804 to avoid delays.
