According to its website, the primary mission of Republicans Abroad is, "To integrate Americans, especially those who adhere to the principles of the Republican Party, into the election process." As such, Republicans Abroad has undertaken social media campaigns to, printed publications, a weekly radio show, and organize Republican voters. The organization has supported Section 911 of the US Code regarding incomes taxes of expatriates, and including expatriates in the US Census.
Until the passage of the Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) in 1975, US citizens overseas could not vote in federal elections. That year, President Gerald Ford signed UOCAVA, thereby enabling voters overseas to cast an absentee ballot in their state of residence. Seeing the need to organize the American electorate overseas Republicans Abroad was started in 1978. Since then, Republicans Abroad has taken an active role in organizing voters overseas, hosting voter registration drives, espousing Republican principles in media, and organizing speakers.
Since February 2009, the organization has hosted a weekly radio show through WSRadio called "Republicans Abroad Radio." The show is aired live each Wednesday from 10:00 AM ET to 11:00 AM ET. Each show is divided into four segments at 10:00 AM, 10:15 AM, 10:30 AM, and 10:45 AM. Guests to the show have included Republicans such as Reagan Attorney General Edwin Meese III, Grover Norquist, and members of Congress.
