Thank you all for information...just to clarify...I wish to add rotor rating to my licence, I received two paths.
1) get a piggypag licence FAA private then adding on that Rotor CPL/IR
2) Get FAA ATP fixed adding to that Rotor CPL/IR
According to news path number 2 seems way more sensitive to get later on an employment worldwide, though more expensive. No way to stay and work in the states.
So I was thinking to get FAA ATP single (fixed), adding rotor/IRl add-on and adding later multiengine fixed if needed.
Any advise about this plan really appreciated.
