Transport Canada(TCCA) to FAA(rotary+fixed wing)

[mehrez]

Hi,
I am the holder of a TCCA ATPL-H and the older of a TCCA CPL-A single engine without IFR.
I am going to have a FAA helicopter ATP certificate(throught my canadian license+the written and flight FAA exams).
And I am going to convert my TCCA CPL-A to a FAA fixed wing CPL certificate(due to the transport canada/FAA agrement)

I would like to know what I have to do to add my fixed wing FAA certificate to my helicopter FAA ATP certificate.
And eventually to add a multi engine and an IFR rating to my fixed wing FAA CPL certificate,knowing that I have an IFR rating with my helicopter certificate with 300 hours instruments,plus around 10 hours of multi-engines and around 10 hours instruments on fixed wing logged with my candian license .

I know it's a very confusing even for me but all help will be strongly apppreciate.

Thank you

Hi did you get your licence converted and an add on?
I am just about to go through something similar, I'm going to convert my Transport Canada CPL(H) to FAA CPL, and a fixed wing add on.
any advice?
