This is a list of some very useful travel apps. I would encourage all of you who don’t have Global Entry Status to download the “Mobile Passport” App. In my international travels, I would estimate that only 10% of travelers coming back to the USA have Mobile Passport.
In many airports the Mobile Passport users get their own special immigration lane. It’s not quite as fast as Global Entry, but it is much faster than using the paper forms like the rest of cattle class.
