Which office provides support for technology-related issues in USCIS?

The Office of Information Technology is responsible for providing support for technology-related issues within USCIS. This office plays a crucial role in managing the agency's technological infrastructure, ensuring that systems operate efficiently, facilitating software development, and addressing any technical challenges that employees may encounter.

The other options do not specifically focus on technology-related support. The Office of Public Engagement deals primarily with outreach and stakeholder engagement, while the Order to Show Cause typically relates to legal proceedings and notifications. The Office of Legislative Affairs is concerned with issues related to legislation and congressional relations, rather than technology support. Thus, the Office of Information Technology is the dedicated resource for technology-related issues within USCIS, making it the correct choice in this context.
