The USPTO refers me to this web page
http://www.uspto.gov/web/offices/pac/doc/general/index.html#treaties
it talks about the Paris Convention for the Protection of Industrial Property which allows me 12 months after the filing date for my US patent. But then It talks about the Patent Cooperation Treaty which says that I can file one application for all the cooperating Countries but it doesn't say how long I have to do it.
Also the USPTO gave me a filing date and they also gave me a different date for when My Foriegn Filing License was Granted. Which date do I go by?
