My passport expires in May, should I go ahead and put that passport number down on the ticket application then contact USSF to update it when my passport shows up?? I've heard some places that you can use your SSN instead which would obviously be the way to go, but I've heard other places that that isn't possible. I also read somewhere that you need to have a valid passport number by the end of January or else you're screwed, in which case I'll need to splurge for the 2-week passport turnaround. BTW I know I'm asking a lot of stupid newbie questions on this forum, in this thread and others, I have absolutely no experience planning any vacations beyond a simple weekend trip to see friends in another city, let alone something of this scale, so I really appreciate everyone who's trying to help me out and point me in the right direction, I've gotten a lot of great advice already. My hope is that others who have similar questions to mine will also see these questions and get clued in themselves, although if this or another of the threads I've started are more appropriate for a pre-existing thread then mods please feel free to go ahead and move them. Thanks again guys and if all goes well see you all in Germany.
