I don't know if you intend to breding also in USA, but anyway you're one oportunity to bring new bloodline to USA, I wonder if wouldn't be better you first enter in contact with the USA breeders and ask for then about the breed situation in the country, which kind of line will be able to improves and be usefull to the dogs in USA.
You see, every oportinity to bring new bloodlines is gold if you can bring a interessing line for the breeding in your country, even if you don't want breed.
