As someone who takes several overseas trips each year, one of the biggest frustrations is the hassle of going through immigration and customs at home. Today I have joined this very clever program and based on the comments on the Web, I am looking forward to the experience of coming home next time. Apparently, everyone who has used it is in love with it and that is what motivated me to join as well.
For just $100 for five years, you get to use a kiosk (it is a sophisticated ATM like machine with capability to check fingerprints in real time) and clear the entry into the US within minutes. You signup online and depending on the backlog, expect to get a conditional approval within days (4 for me). Then just go to the nearest airport for fingerprinting and document check (whole process took 2 minutes for me at Boston Logan Airport).
