Although many paths may lead to the presidency of the United States, the most common job experience, occupation or profession of U.S. presidents has been that of a lawyer.^[1] This sortable table enumerates all holders of that office, along with major elective or appointive offices or periods of military service prior to election to the presidency. The column immediately to the right of the presidents' names shows the position or office held just before the presidency. The next column to the right lists the next previous position held, and so on. Note that the total number of previous positions held by an individual may exceed four; the number of columns was limited to what would fit within the page width. The last two columns on the right list the home state (at the time of election to the presidency) and primary occupation of each future president, prior to beginning a political career.

There have been 46 presidencies (including the current president, Joe Biden, whose term began in 2021), and 45 people have served as president. Grover Cleveland was elected to two nonconsecutive terms, and as such is considered the 22nd and 24th president of the United States. Of the 45 different people who have been or are currently serving as president:

• 32 presidents had previous military experience; 9 were generals in the US Army.^{[lower-alpha 1]}

Johnson served in Tennessee during the Civil War.
• 18 presidents previously served as U.S. representatives; 6 of 18 held this office prior to the four 'previous positions' shown in this table. Only one – James A. Garfield – was a representative immediately before election as president. Only Garfield and Abraham Lincoln had served in no higher office than representative when elected president. Only John Quincy Adams served as a U.S. representative after being president. Additionally, after being president, John Tyler served in the Provisional Confederate Congress and was later elected to the Confederate House of Representatives, but he died before taking his seat.^[3]

Taylor, Grant, and Eisenhower led U.S. forces to victory in the Mexican–American War, American Civil War, and World War II, respectively – each occupying the highest-ranking command post of their time. Trump is the group's sole exception, having never held any public office nor any military position.
