Can a Global Entry-registered person choose to use the standard immigration lines?
My wife and I travel to the USA occasionally, sometimes together, sometimes separately. Currently we both have ESTA registrations.
My understanding is that in order to join the Global Entry system we will each need to be interviewed while in the USA. It is quite likely that we may join Global Entry on different occasions and hence the possibility arises that we may enter the USA together when we both have ESTA but only one of us has completed the Global Entry process.
While we could separate at immigration each going to our own lines this just adds complexity; much prefer to keep together. That implies we'll both need to follow the slow immigration line. I can't see why this should be an issue, but I can find any guidance on the topic.
