Will FAA issue CPL based on foreign license as well, providing that you have got FAA PPL based on foreign license conversion. And you even meet the requirements of FAA CPL (Hours and all other odds and ends) based on your previous experience and you have a foreign CPL/IR as well and now want to get FAA CPL based on it (Does it only require you to write CPL and IR test paper and checkride, or just a few hours with FAA CFI? or no a complete start from the scratch onward PPL?)
