The next time I need passport help, I plan to use an iPhone app called My Passport & Visa App.
The publishers of this app have collected and organized all of the information a US citizen would need to know about applying our renewing a passport or visa. The app includes information about application forms and a set of video tutorials showing how fill them out.
Users can also find locations where they can apply in person, options for getting a passport photo, a list of services such as Rush Passport Center that will expedite the passport process for a fee and a link to track your package when you send documents.
The app is a free downloading the iTunes App Store. I works on iPhones, iPads and the iPod Touch.
