Bump. Very interested in whether this worked out? I need to head to the US for a couple of work meetings later this year.

My chip (UK passport) has never worked. I've had it since 2013. I'm concerned the new measures will make it difficult for me to gain entry.

I have the added complication of a Somaliland visa/stamp in my passport (which is Somalia for government purposes), and therefore probably need to get a visa before I travel. I just don't know if I need to get a replacement passport before the visa.

Also have various trips booked between now and the US trip so have to plan my passport stuff carefully.

Can anyone shed any light on the RFID chips, and whether they need to be functioning to gain entry to the US? I've been told several times by UK border staff that I cannot go to the US with a broken chip.
