Flew back from Edinburgh, Scotland via Schiphol airport in Amsterdam (it was meant to be direct, thanks United!) yesterday with my wife and landed at ORD. The immigration officer told me that everyone with an extension letter needs to get sent to secondary because of process reasons 🤷♂️. I was in secondary for about 15-20 minutes, which seemed to be because of the volume of people there. An officer brought my documents out of a backroom and handed them to another officer who asked me to confirm my date of birth and then they sent me on my way.
 
	 
 
	Not the smoothest experience but not my first rodeo in secondary either.
