Which of these does NOT restrict submitting investigations for security eligibility?

The option indicating that government personnel requesting through e-QIP does not restrict the submission of investigations for security eligibility is correct because government personnel are actually required to submit their requests through the e-QIP system, which facilitates the process of conducting background investigations. Using e-QIP is a standard procedure for government employees to maintain secure and efficient processing of their security clearance applications.

The other choices imply various restrictions based on employment status or legal history. For instance, civilians in sensitive positions, individuals with prior convictions, and non-U.S. citizens face specific limitations or additional scrutiny in the security clearance process. In contrast, government personnel utilizing e-QIP are not restricted in the same manner; rather, they are following the established protocol, making their option the one that does not impose restrictions on submitting investigations for security eligibility.
