The Challenge

The U.S. Department of State’s Bureau of Consular Affairs Office of Consular Systems and Technology (CA/CST) faced a critical challenge in 2017: how to modernize and architect one of the world’s most complex consular technology ecosystems while maintaining 24x7x365 operations across 230 overseas locations and over 30 domestic sites.

The Bureau’s existing technology landscape presented significant architectural challenges. Legacy systems had evolved organically over decades, resulting in a complex mix of technologies that included over 300 Oracle and Microsoft SQL Server databases, .NET applications, PowerBuilder desktop applications, and point-to-point integrations. 

With the ambitious ConsularOne modernization initiative underway, CA/CST needed independent systems engineering expertise to guide this transformation while maintaining operational continuity. The Department required a partner team who could provide unbiased architectural guidance, evaluate implementation approaches, and develop engineering standards that would govern future system development efforts.

Our Approach

When Prime Source Technologies joined the Research Innovation Systems Engineering (RISE) team as a key subcontractor to Xfinion, we recognized this wasn’t just a technical architecture project – it was an opportunity to shape the future of global consular operations. As part of the winning team, PST brought our specialized expertise in enterprise system architecture, systems engineering, and federal technology modernization to support this critical Department of State initiative. Our role within the RISE team leveraged PST’s core strengths in complex system integration, architectural evaluation, and engineering standards development. Working collaboratively with Xfinion and other team members, we contributed our deep understanding of federal system requirements and proven methodologies for managing large-scale technology transformations.

As a critical member of the RISE team, PST’s comprehensive contributions focused on six core areas:
