Now, Therefore, I, Ronald Reagan, President of the United States of America, by the authority
vested in me by the Constitution and the laws of the United States, including section 3(d) of the

amendments to the Convention shall be effective on and after June 1, 1983, for the United States
of America, the citizens of the United States of America, and all other persons subject to the
jurisdiction of the United States of America.
In Witness Whereof, I have hereunto set my hand this 16th day of June, in the year of our Lord

two hundred and seventh.
