Question about passports for travelling to US?
I have an older style British passport without the memory chip, mine has the barcode as it was issued in 2002. Is this type of passport still ok for using to travel to the US, or do I need to get the memory chip passport?

Best answer:

Your passport is fine. The barcode makes it machine readable, which is the requirement to enter the U.S. under the visa waiver program. Have a great trip.
