Are you referring to a 61.58 PIC check?
if not, there is no requirement for an annual IR: maintain your “6 in 6” currency, and never have to do another IPC.
Also, unless you are a US citizen, you will still require TSA processing, even for recurrent training outside the US.
This is one of the responsibilities mentioned when acting as an ‘Authorised’ instructor or examiner under FAA regs.
Good luck.
