The main purpose of this legislation, known as the Valid Benefits Act, is to ensure that individuals who are 105 years old or older continue to qualify for federal benefits. The law aims to establish a system for verifying the eligibility of these elderly individuals for the benefits they receive. Key provisions of the Act require the heads of federal departments and agencies that provide benefits to people aged 105 and older to check their eligibility every six months. This means that these agencies must take steps to confirm that individuals still meet the criteria for receiving benefits.
