In the United States, a presidential transition is the process during which the president-elect of the United States prepares to take over the administration of the federal government of the United States from the incumbent president. Though planning for transition by a non-incumbent candidate can start at any time before a presidential election and in the days following, the transition formally starts when the General Services Administration (GSA) declares an “apparent winner” of the election, thereby releasing the funds appropriated by Congress for the transition, and continues until inauguration day, when the president-elect takes the oath of office, at which point the powers, immunities, and responsibilities of the presidency are legally transferred to the new president.

The General Services Administration (GSA) is an independent agency of the United States government established in 1949 to help manage and support the basic functioning of federal agencies. GSA supplies products and communications for U.S. government offices, provides transportation and office space to federal employees, and develops government-wide cost-minimizing policies and other management tasks.
