FWIW, training done by an ICAO compliant instructor like EASA, can count towards the training requirements of an FAA pilot certificate even if done in a non US aircraft. However the sign off to take a check ride needs to be carried out by an FAA certified instructor along with at least 3 hours of training.
Instrument training for an IMC rating only counts towards the instrument training requirement if the instructor is an IR instructor as that is ICAO compliant.
