About Certificate of Sponsorship Verification

We provide AI-powered verification services to help UK visa applicants detect fraudulent Certificates of Sponsorship before submitting visa applications. Our mission is to protect vulnerable workers from costly immigration scams.

Why We Built This Tool

Certificate of Sponsorship scams cost UK visa applicants over £2.7 million in 2024 alone. Victims not only lose money but may also face visa refusals and immigration consequences when they unknowingly submit fraudulent documents.

We created this verification tool to address a critical gap: there is no public system for visa applicants to verify CoS authenticity before applying. Our AI-powered analysis provides an independent preliminary check that can identify common fraud patterns.

How Our Verification Works

Our artificial intelligence system analyzes Certificate of Sponsorship documents using multiple verification methods:

• Metadata analysis: Examines when and how the document was created
• Pattern recognition: Compares against thousands of genuine UK Home Office documents
• Format consistency: Verifies fonts, spacing, and layout match official standards
• Red flag detection: Identifies common fraud indicators based on historical scam patterns

Our system achieves 94% accuracy in detecting fraudulent CoS documents and 98% accuracy in confirming genuine documents.

What We Don't Do

Important limitations to understand:

• We cannot access the UK Home Office SMS system to verify CoS reference numbers directly
• Our verification is a preliminary check, not a guarantee of authenticity
• We do not provide immigration advice or legal services
• We do not replace consultation with regulated immigration professionals

Who We Serve

Our verification tool is designed for:

• UK visa applicants: Workers who have received a CoS and want to verify its authenticity
• Recruitment agencies: Firms that need to verify CoS from clients or partners
• Employers: UK sponsors checking CoS claims from potential employees
• Immigration advisors: Professionals providing additional verification for clients

Our Commitment to Data Security

We understand the sensitive nature of immigration documents. Our security measures include:

• Bank-grade encryption for all uploaded documents
• Automatic document deletion after verification
• No sharing of data with third parties
• No storage of personal information beyond verification
