A couple of years ago, somebody (a US citizen) arriving in the USA from France got pulled over by Customs because of carrying an apple in her hand baggage. She was prosecuted (fined around $500) and had her Global Entry status revoked. As the Global Entry only pertains to Immigration and not Customs, one would expect the withdrawal of Global Entry to be because of an Immigration violation (e.g. misuse of Global Entry) rather than a Customs violation.
Actually I also believe that she was subjected to the requirement for increased TSA screening on future flights (even domestic). But TSA has nothing whatsoever to do with Customs and Border Protection (CBP), and nor do they have the remit to enforce CBP rulings. So how did Customs and TSA end up being dragged into this, when it is purely an Immigration issue? Would she subjected to comparable restrictions when crossing the border by land?
And on a related matter, now imagine that she subsequently tries to enter a foreign country having acquired this criminal record: We know very well that Immigration violations committed anywhere in the world will automatically show up on our passport record, and any country reserves the right to refuse entry to non-citizens.
Do Customs violations also automatically show up on our passport record, and can therefore also result in entry being refused to non-citizens? Or are Customs violations treated as a purely domestic matter (like any other domestic crime), and for the (foreign) Immigration department to find out this information they have to make a special request to the government database of the relevant country (in this case USA)?
Apologies for the lengthy post, but this is a very grey area that needs clarifying, and thanks in advance to those who can answer this.
