CSIS Wadhwani Center for AI and Advanced Technologies — Headquarters: Washington, DC

Note: The source text is about the Center for Strategic and International Studies (CSIS) itself, not specifically about the 'CSIS Wadhwani Center for AI and Advanced Technologies.' While the source confirms CSIS's main headquarters is in Washington, DC at the address provided, it does not address whether the Wadhwani Center (which appears to be a center or initiative within CSIS) has its headquarters at that same location or elsewhere. The claim conflates the parent organization's headquarters with a specific center within it, which the source does not clarify.

Note: The source text explicitly confirms that CSIS's headquarters is located at 1616 Rhode Island Avenue NW in Washington, DC. This matches the claim exactly, including the specific address provided in the additional context. The Wikipedia article clearly states both the street address and the city/location.
