How Nigerians in the UK Can Spot a Fake CoS – And What To Do Before It Expires in 3 Months

📢 Your Certificate of Sponsorship (CoS) could change your life.
If a UK school, hospital, or employer offers you sponsorship, this is the official record that allows you to apply for a Skilled Worker visa.

But here’s the shocker:
👉 Some Nigerians have received fake CoS documents from unlicensed recruiters.
👉 Others have allowed their real CoS to expire after 3 months because they didn’t act fast.

Let’s break down what you need to know to protect yourself and secure your future in the UK.

🧐 What Exactly Is a Certificate of Sponsorship (CoS)?

Despite the name, it’s not a physical certificate. It’s an electronic record issued by a licensed UK employer in the Home Office system.

When assigned to you, your employer will send you details by email, including a CoS reference number. You must enter this number when applying for your Skilled Worker visa.

✅ What You’ll See on a Genuine CoS

1. CoS Reference Number – A unique 10–12 digit code you’ll use in your visa application.
2. Your Details – Name, date of birth, nationality, passport number.
3. Sponsor Details – Employer’s name, sponsor licence number, and registered address.
4. Job Information – Title, occupation code, salary, start date, and end date.
5. Maintenance Status – States if your employer will cover your £1,270 settlement funds.
6. Extra Notes – Such as relocation support or confirmation that your role is on the shortage list.

🚩 How to Spot a Fake CoS

Sadly, fake recruiters prey on Nigerians hoping to relocate. Here’s what to watch out for:

• ❌ No Sponsor Licence Number – Every legitimate UK sponsor must have one.
• ❌ Incorrect Job Codes – Check that your job matches the official Skilled Worker list.
• ❌ Suspicious Employer – Cross-check the company on the official UK Government Register of Licensed Sponsors.
• ❌ Upfront Payment Demands – Genuine employers do not ask candidates to pay for a CoS.

If something feels “off,” it probably is. Always verify before celebrating.

⏳ Your CoS Expires in 3 Months – Don’t Waste It

A CoS must be used within 3 months of being issued. If you miss this deadline, it expires — and you may lose your job offer.

🔑 What You Must Do Immediately After Receiving a CoS:

1. Check Details Carefully – Ensure your name, passport, and job info match exactly.
2. Gather Visa Documents Early – TB test (if required), proof of English, police clearance, bank statements (if maintenance not covered).
3. Book Your Visa Appointment ASAP – Don’t wait until the last week; slots fill quickly.
4. Stay in Contact With Your Employer – They must confirm your start date and support your application.
5. Plan Financially – Have your visa fee, NHS surcharge, and flight costs ready.
