My 1 year old grandson will be travelling with us in april.
We are just getting his first passport and I noticed this comment on the Homeland security site, can anyone shed any light on this matter please.

e-Passports. The United States requires that travelers entering the United States under the Visa Waiver Program have an e-Passport if their passport was issued on or after October 26, 2006.

I have also asked them if they can clarify when the ESTA program will be fully operational.
