Might be worth checking that out. That would mean that you do not need to get any form of FAA PPL (standalone or piggyback), but do the CPL flight test straight away.
That's not going to work in the US for the CPL.
For the FAA ATP you need either a US CPL IR or an ICAO CPL-IR, for the US CPL you need a Full US PPL or the restricted one.
Checkerb, if you intend to do the US CPL I would advise to do the training for the full US PPL iso the restricted license.
Night can not be added to a US PPL since it is included.
So if you hold a US "restricted" based on a foreign license with no night rating you are not allowed to fly at night.
Which would lead to an IR which you cannot use at night and there is no way to fly the required PIC night hours for the CPL.
So either add the night rating before you come to the US or plan on doing the US PPL.
