My 17-year-old son is a dual US-UK citizen and is travelling to the USA this summer on his own. I have been told U.S. Customs and Border Protection (CBP) recommends that the child carries a notarized written consent letter from both parents, in case it is requested for review by US immigration officials.
Does anyone have a link to an example letter to show what this should look like?
Does he need to bring an original of his birth certificate or any other documents?
Also, regarding the notarization, does this have to be done as per US guidelines or UK guidelines? I understood that in the UK the equivalent of US notarization would be a solicitor's/lawyer's signature witnessing the signatures or for example having this done by a bank. Would this be sufficient, as the cost of having something notarized in the UK is quite expensive.
