Which of the following activities would likely disqualify someone from receiving classified access?

Owning property in another country is a significant factor in security clearance evaluations. This activity can raise concerns regarding potential foreign influence or allegiance. When a person owns property abroad, it may open them up to pressures or relationships that could compromise their loyalty or judgment, especially if the foreign country has differing interests from the United States. Security clearances are designed to protect sensitive information, and any ties to foreign entities can be viewed as a risk, prompting scrutiny during the vetting process.

In contrast, the other activities mentioned, such as volunteering locally, regular family travel, and attending professional conferences, are generally seen as benign or even positive. They do not inherently suggest a risk of compromise or conflicting loyalties. Thus, while all activities are evaluated in a comprehensive background check, property ownership in another country is a more significant red flag regarding classified access eligibility.
