With respect to the Presidential Executive Order: Protecting the Nation From Foreign Terrorist Entry Into the United States and the people affected by it and further to the special case of people travelling to Massachusetts, is there anyone (or organisation) to contact prior to travel that may be helpful in transiting US immigration controls? Publications or guidance from a nationally recognised and accredited legal resource would be welcomed here.
Secondarily, are there any specific documents a traveller should carry with them with a view towards presenting them if need be? Links to specific documents that should be printed out and carried in hand luggage? Seeking qualified and informed answers.
NOTE: Answers to the so-called 'canonical' question contain excepts from news stories only. These can be obtained by a simple Google search and provide no clearly defined information of use to an individual traveller. Or in other words, they do not give specific advice to the traveller about how to best prepare for an adverse encounter event with US authorities. The 'canonical' question (a collection of news items that simply rehashes a Google search) does not address that problem.
Apart from the above, Solicitor Christi Jackson just gave an interview on BBC World which provides some information for travellers that might be helpful. Citations welcomed. Her colleague, Karnig Dukmajian, also spoke on BBC World earlier today.
