Received my new passport a few weeks ago, so decided as we have a month before our Denver trip to apply for my new ESTA. Think I filled it in ok then its now put me on pending authorisation, have never had this before and of course got me panicking. Anybody else had this with a new passport? Or could something else be amiss. Linda
It will be because you are on a new passport. My Dad had the very same thing despite numerous trips to the US, once he re-applied with a new passport he had to wait 24 hours or so to be approved.
I wouldn't sweat it
