In June 1910, the first major expansion of the bureau happened, when the Mann (White Slave) Act was passed. The Act made it a crime to transport women over state lines for immoral purposes (fbi.gov, 3). The FBI began with thirty-four special agents, and within the next few years, the number of Special Agents had grown to more than three hundred, and another three hundred support employees (fbi.gov, 3). With the entry of the United States into World War I in April 1917, the bureau's jurisdiction was enlarged to include espionage, selective service, sabotage acts, and assisted the Department of Labor by investigating enemy aliens.

When the FBI began, it did not have the jurisdiction that it has today, because the Bureau was originally set up for investigation banking, bankruptcy, naturalization, antitrust, espionage, and land fraud. Today, the FBI has pretty much an unlimited jurisdiction anywhere in the world, because the FBI investigates any crime that is in anyway related to the United States.

There were to main causes to the FBI's jurisdiction to be enlarged, first was in 1929 when the stock market crashed and following that was the Great Depression.
