Failure or inability to live within one’s means, satisfy debts or meet financial obligations may indicate poor self-control, lack of judgment or unwillingness to abide by rules and regulations, all of which can raise questions about an applicant’s reliability, trustworthiness and ability to protect classified national security information (CNSI). An individual who is financially overextended is at risk of having to engage in illegal acts to generate funds. Compulsive gambling is a concern as it may lead to financial crimes including espionage. Affluence that cannot be explained by known sources of income is also a security concern. It may indicate proceeds from financially profitable criminal acts.
