Any profession that requires federal licensing is likely to be prominent and lucrative,
but it's also likely to involve a business too big for one individual to run. Big national industries
involving public safety are likely to be regulated at the federal level.
industry, for example, is regulated by the Federal Aviation Administration, which issues
certifications for aircraft, airlines, airmen, airports and commercial space transportation.
The United States Department of Agriculture (USDA) and the Food and Drug Administration (FDA)
provide certifications and approvals affecting businesses that sell food products. The broadcast industry, whether local or national, is regulated by the Federal Communications Commission.
The Federal Energy Regulatory Commission (FERC) licenses and inspects private, municipal and
state hydropower infrastructure projects.
In general, the federal government plays less of a licensing role than state agencies, but
the federal government is influential at setting national industry standards that
become the basis for state training and certification. The best place to do further research
