Presidential Proclamation 4771 on July 2 , 1980
A Proclamation
Section 3 of the Military Selective Service Act, as amended (50 U.S.C. App. 453), provides that male citizens of the United States and other male persons residing in the United States who are between the ages of 18 and 26, except those exempted by Sections 3 and 6(a) of the Military Selective Service Act, must present themselves for registration at such time or times and place or places, and in such manner as determined by the President. Section 6(k) provides that such exceptions shall not continue after the cause for the exemption ceases to exist.
The Congress of the United States has made available the funds (H.J. Res. 521, approved by me on June 27, 1980), which are needed to initiate this registration, beginning with those born on or after January 1, 1960.
Now, Therefore, I, Jimmy Carter, President of the United States of America, by the authority vested in me by the Military Selective Service Act, as amended (50 U.S.C. App. 451 et seq.), do hereby proclaim as follows:
1-1. Persons to be Registered and Days of Registration.
1-101. Male citizens of the United States and other males residing in the United States, unless exempted by the Military Selective Service Act, as amended, who were born on or after January 1, 1960, and who have attained their eighteenth birthday, shall present themselves for registration in the manner and at the time and places as hereinafter provided.
