Whoa!! - the piece of paper that an AMERICAN flight examiner gives you will allow you to carry passengers (girlfriends).
If Prophead only continues training towards, and sits the skill test for, a JAA PPL then he will NOT be allowed to carry passengers, as the piece of paper given by a JAA flight examiner is NOT a licence and carries no passenger privileges.
Six weeks should be enough for visa - GET ON WITH IT (as said above).
Enjoy the flying.
