No transit visa

F*?CK!! I am panicking again. One of my colleeges told me that he had a transfer flight in the US and his wife had an old passport, and they had problems getting trough.I don´t have a transit visa, and I would not need to have one if I would have one of those new passports, but I have an old one, and I am not sure what the policy is with an old passport. I have been calling around all day and looking up info on the net, and I am getting mixed messages. The american embassy has not been open today, and they are the only ones who can give a definite answer.A transit visa should apperantly be issued immediately, so if I need one, I can hopefully get one on monday.Damn it! I am nervous about not being able to travel to Panama at all..... :/
