There is nothing stopping that kind of thing.
The only issue with something like that in terms of workers is that the workers have to originate in the country that we've signed a side deal with. In terms of contractors, it might end up being a Spanish country, but in fact we'll only accept the workers from the five side deal countries, so they'll have to show admissibility based on their being from Mexico, and the list goes on, Peru, or Australia.
The companies are one thing, but the workers would have to come from a country of origin and be admissible under TPP.
