01 — TECHNICAL PROPOSAL

UAE Visa Processing Platform

Production-grade, on-prem, hybrid multi-agent platform for UAE visa, residency, and Emirates ID request processing.

Executive Summary

Platform Overview

This platform defines a production-grade, on-prem, hybrid multi-agent system for UAE visa and Emirates ID request processing. It supports two critical journeys:

→

Submit Request

Create a new visa, residency, or Emirates ID application with full eligibility validation, form filling, document processing, booking, and payment.

↻

Request Status

Check and track status for an existing application with poll/push updates, loop-back handling for incomplete requests, and real-time notifications.

The Solution Combines

  • Agent orchestration for high-level reasoning and workflow control
  • Deterministic tool-calling for government API integrations
  • Policy-driven business rules compiled from SKILL.md (English) into versioned YAML
  • High-throughput architecture designed for 6,500 requests/minute peak
  • Processing of large historical and operational datasets (30-50 million applications)
Scope

Goals & Non-Goals

Goals

  • Build a scalable processing platform for visa and Emirates ID services with support for large traffic spikes
  • Convert business rules in SKILL.md into executable YAML definitions used by runtime agents
  • Orchestrate Submit Request and Request Status flows with traceable step-by-step reasoning
  • Integrate with multiple government and partner APIs through secure, resilient tool interfaces
  • Provide operational observability, audit trails, and compliance-ready data retention

Non-Goals

  • Replacing source government systems (ICP/MOHRE/DOH/TAMM/etc.)
  • Building a standalone BI data lake in this phase
  • Implementing all citizen services beyond the current visa/residency/EID scope
Domain Analysis
