The president's appearance at the theater will be preceded by a visit to a private home in Piedmont. The president is expected to make remarks at the Fox around 8 p.m.
Outside the theater, groups representing a number of causes are planning protests.
Medical marijuana patients and advocates, including the group Americans for Safe Access, will be rallying throughout the afternoon to protest what they call a federal crackdown on the medical marijuana community and Oakland's dispensaries.
There will also be a number of anti-war protests, including one conducted by Afghans for Peace and the San Francisco Bay Area Iraq Veterans Against the War. The protesters, who will include members of Occupy Oakland, will call for an end to wars abroad in what they are calling an "Unwelcome Obama" demonstration.
Undocumented immigrants will protest on behalf of detainees awaiting deportation who would be allowed to stay in the country if the DREAM Act were passed.
Representatives of the nonprofit Center for Biological Diversity, along with the group's mascot, Frostpaw the polar bear, will be on hand to speak out against oil drilling in the Arctic.
The protesters will all be convening in downtown Oakland with hopes of getting as close to the Fox Theater as possible. Police are planning a number of road closures to accommodate the president's visit.
