And what is the nature of the agreement on Social Security between the UK and the USA ?
So that you can't claim any further ignorance, here is part of a relevant parliamentary answer from 2002:
Mr Malcolm Wicks (Parliamentary Under-Secretary said:
The main purpose of such reciprocal agreements is to protect the social security position of workers moving between the two countries during their working lives. They prevent employees, their employers and the self-employed from having to pay social security contributions to both the home state and the state of employment at the same time and ensure that such workers' rights to certain benefits are maintained.
An Order is an 'Order', isn't it ?
No
Who is actually giving the Order?
It's not that kind of order, it's a Statutory Instrument.
The text says it's an Order made by the UK Crown, doesn't it ?
The text says it's an agreement:
IN WITNESS WHEREOF, the undersigned, being duly authorised thereto by their respective Governments, have signed this Supplementary Agreement.
DONE in duplicate at London on 6th June 1996.
FOR THE GOVERNMENT OF THE UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND:
William Marsden,
(Americas Director, FCO)
FOR THE GOVERNMENT OF THE UNITED STATES OF AMERICA:
Timothy E. Deal,
(Minister, Embassy of the United States of America)
And it's Crown Copyright, isn't it ?
So? All works produced by the British government are crown copyright, it refers to the office and not the specific sovereign.
An order is not an agreement. It's an Order. Isn't it ? There IS a difference between an agreement and an order, isn't there ? And what is the UK Crown doing issuing Orders on US Social Security ?
A little reading before ranting would provide all the information you require.
