Internal Affairs Administration

The Internal Affairs Administration, also known as Affairs, is a Terran agency dependent of the Federal Ministry of the Interior. It is led by the Committee on Affairs of the Interior, comprised of seven or nine comissioners. Its primary tasks are to eliminate tax fraud, ensure the fairness of elections, maintain influence of the federal government at a local level and prevent illegal immigration. 
The IAA was founded by the fourth chancellor of the Federation, Tanya Abrams in 2132. At the time, the primary and only concern of the agency was to ensure the fairness of elections. The 2127 elections had been plagued with controversy, and chancellor Abrams wished to eliminate such issues of legitimacy for any future government. Following the 2133 election, the IAA's role was expanded to the fighting tax fraud along the Bureau of State Security. 
With Terran expansion to other systems, the number of instances of commonwealths trying to circumvent federal law or to disobey it increased drastically. This became a major issue following the year of 2301, when the combined population of all other worlds surpassed that of Earth. To ensure federal control, the IAA was tasked with monitoring leaders of commonwealths across the Federation and eliminate dissent. Since the Great Galactic war, a great number of alien immigrants moved to the Federation. Initially, there were few to no ways for aliens to legally immigrate to the Federation. Affairs was tasked in 2651 to prevent any and all illegal immigration. Following the Détente of 2666, illegal immigration fell to a near insignificant level. Nevertheless the IAA is still tasked with eliminating illegal immigration. 
Affairs has no subdivisions. It is led by the Central Comittee, which answers to the Minister of the Interior. The Comittee and the agency's headquarters are located near the Ministry in Johannesburg on Earth. Whilst similar to the BFS, it is much smaller and has a lesser number of agents. The agents are however spread more evenly across the Federation, proportionally to population rather than to crime rates.
