Technically, you can use the egates. But not all passports will work. Sometimes there is a problem with the egates reading the computer chip in your passport. That is what always happens to me. So, if the egates don't work, you have to wait to talk to an immigration agent. This is not the main immigration line but a separate one for those in the same situation. It all depends on who is on the desk. Usually it's one or two questions and I'm through. In April, the guy on the desk was checking each page with a special light to make sure the passport was real.
I don't even bother with the egates anymore.....I go straight to this special line.
Either way, you will have to remove your mask so the photo in the passport can be matched with your face. Assuming you're wearing a mask.
