4 Pa. Code § 171.12 – Absentee registration for President and Vice President.

(a) A person qualified to vote for President and Vice President under the provisions of the 1970 Voting Rights Act Amendments (42 U.S.C.A. § 1973aa et seq.) as described in the opinion of the Attorney General which appears at 2 Pa.B. 1913, shall be allowed to register absentee for the purposes of voting for the President and Vice President if they submit the following affidavit:
I hereby swear (or affirm) that I am unable to register in person by reason of absence from my election district, that on the day of the next ensuing election I shall have been a citizen of the United States for at least one month, that I will be 18 years of age, on the day after the election, that I will have been a resident of the Commonwealth and my election district for at least thirty (30) days, that I will be legally qualified to vote, and that I have read (or have had read to me) the foregoing statements made in connection with my registration and that they are true and correct.
(b) Final application for absentee registration may only be honored during the time the registration books are open.
(c) As with absentee balloting, absentee registration for purposes of Presidential and Vice Presidential balloting under the 1970 Voting Rights Act Amendments (42 U.S.C.A. § 19733aa et seq.) shall be extended without reference to the reason for the absence. Absence from the election district refers to an absence during such times as the registration books are open. Further, that an individual who affirms that he is a qualified absentee elector shall be permitted to register absentee for purposes of Presidential and Vice Presidential elections. Challenges to registrations shall come under relevant provisions of Commonwealth law governing challenges to registered voters. An election official who refuses to register or forward an absentee ballot to a voter who has properly completed the required affidavit subjects himself to the penalties provided under Federal and Commonwealth laws.
