First thing is that, before you can get the 'no applied IF' restriction removed from your FI rating you must get the '(R)' bit removed. The old AFI rating did not have this problem.
If you hold a UK CPL then you have the priviliges of an IMC rating so you can teach for it (once the restrictions are removed). If you have a JAA CPL then you don't have the IMC; howver, the IR can count as an IMC rating for 25 months, although you would need to have some form of licence endorsement to that effect.
Check out the 'Instructing for Instrument Rating' thread. Watford rarely speaks with forked tongue!
