Visa Scam Warning
How to Spot UK Visa Sponsorship Job Scams: A Checklist for Nigerian Applicants
Real UK sponsorship jobs exist — and so do thousands of fake ones built to take your money, your passport details, or both. This guide shows you how to test any offer in a few minutes before you pay anyone a naira.
Why Nigerian job seekers get targeted so heavily
Scammers follow demand. Interest in UK work visas among Nigerians is high, the rules are complicated, and most applicants have never seen what genuine sponsorship paperwork actually looks like. That gap is exactly what fraudsters sell into.
The typical setup is cheap to run: a borrowed company logo, a WhatsApp number, a PDF "offer letter", and a bank account. One operator can message hundreds of people a day and only needs a handful to pay.
The good news is that UK sponsorship is one of the most checkable systems in the world. Almost every fake offer falls apart against two or three free checks you can do from your phone.
Check the employer on the official sponsor register first
No UK employer can sponsor a work visa unless the Home Office has granted it a sponsor licence. The Home Office publishes the full list of licensed sponsors on GOV.UK as a downloadable register, updated regularly.
Search the register for the exact organisation name. If the company that "offered" you a job is not on it, the offer cannot lead to a visa — full stop. Also check the route: a company licensed for one visa type cannot sponsor you on another.
Watch for near-miss names. Fraudsters copy a real licensed sponsor and change one letter, add "Ltd", or invent a "recruitment division". Compare the name character by character, then find the employer's own website independently through a search engine rather than any link sent to you.
The money test: what you pay, and what you never pay
You do pay some official costs yourself — the visa application fee, the immigration health surcharge, biometrics, a tuberculosis test at an approved clinic (required for applicants from Nigeria), and an approved English test if your route needs one. These are paid to official channels: GOV.UK, the designated visa application centre, or the test provider directly.
You should never pay an employer or agent for the job itself. Under UK rules, recruitment agencies cannot charge work-seekers a fee for finding them work in most sectors, and sponsors are not allowed to pass on costs such as the immigration skills charge or sponsor licence fees to the worker. Anyone demanding a "sponsorship fee", "CoS fee" or "slot payment" is either breaking the rules or lying about having a job at all.
Payment method is a giveaway. Personal accounts, crypto, gift cards, third-party "agents in Lagos", or money sent to someone's relative are all signs you are being harvested, not hired. So is a "refundable" deposit to "secure the slot" before any interview.
Red flags in the advert or message itself
No interview, or a two-minute chat on WhatsApp followed by an instant offer. Real UK employers interview — usually by video — and ask about your qualifications, registration and references.
Guarantees. Nobody can guarantee a visa, because the decision belongs to the Home Office, not the employer. Phrases like "100% visa assured", "direct Home Office connection" or "we have an insider" are marketing for fraud.
Vagueness about the job. Genuine listings name the employer, the site, the role, the hours and a salary that matches UK rules. Fakes advertise "UK factory jobs, no experience, free accommodation, £4,000 monthly" with no employer name.
Pressure and secrecy. Deadlines of 24 hours, "only 3 slots left", instructions not to discuss it with anyone, and contact only through WhatsApp or Telegram using free email addresses rather than a company domain.
Fake certificates of sponsorship and fake Home Office emails
A certificate of sponsorship is not a certificate you receive by email as a decorated PDF. A licensed sponsor assigns it electronically and gives you a reference number, which you enter in your visa application. Any glossy "CoS document" sent as an attachment with a request for payment should be treated as fake.
Be just as sceptical of "Home Office" or "UK Visas and Immigration" emails. Check the sending domain carefully — official UK government addresses end in gov.uk, not lookalikes with extra words or different endings. Government bodies do not ask you to pay fees into private bank accounts.
The same applies to "approval letters", "visa reference numbers" and screenshots of application portals. If you cannot verify something inside your own GOV.UK application or with the employer through a number you found yourself, assume it is manufactured.
Verify the person, not just the company
Fraudsters impersonate real recruiters at real companies. So verify the human being. Find the employer's phone number or contact form on its own website — not in the message you received — and ask whether that person works there and whether the vacancy exists.
Look the company up on Companies House, the UK's free register of companies, to see whether it exists, when it was incorporated and whether it files accounts. A company registered three weeks ago that is suddenly recruiting fifty overseas workers deserves hard questions.
For health and social care roles in England, providers must be registered with the Care Quality Commission, and you can search that register online. Note too that UK rules on recruiting care workers from overseas have been tightened in recent years, so treat any mass "care job" campaign as needing extra verification on GOV.UK.
Protect your documents and your data
Many of these operations are not after your money at all — they want your identity. Scans of your passport data page, your NIN or BVN, bank statements and a selfie holding your ID are enough to open accounts or build a fraudulent visa application in your name.
Share documents only after you have confirmed the employer is a licensed sponsor and the vacancy is real, and only through channels the employer controls. No legitimate employer needs your bank login, your BVN, or an OTP from your phone.
Never hand your original passport to an agent. You submit it yourself at the official visa application centre. If someone is holding your passport and asking for more money to "release" it, that is coercion, not recruitment.
If you have already paid or shared details
Act fast and in writing. Tell your bank immediately and ask about a recall or chargeback; keep every chat, receipt and account name as evidence. If your BVN or bank details went out, ask your bank about blocking and monitoring.
In Nigeria, you can report financial fraud to the police and to the Economic and Financial Crimes Commission. Where the fraudster or company is in the UK, fraud can be reported to Action Fraud, the UK's national reporting centre, and suspected immigration crime can be reported through the relevant GOV.UK page.
Also warn others in the group or page where you found the advert, and report the profile on the platform. Most of these accounts survive because nobody reports them.
A 60-second check before you reply
Is the employer on the Home Office register of licensed sponsors, spelled exactly? Does the company exist on Companies House with a real trading history? Did you find its contact details yourself rather than in the message?
Has anyone asked you for money for the job, the sponsorship or a "slot"? Have you had a proper interview? Is the salary and job description consistent with UK rules on GOV.UK rather than a dream figure?
If any answer is wrong, stop. Walk away from one suspicious offer and you lose nothing; the real routes are still open, and official information about them is free on GOV.UK.
Common questions
Is it illegal for a UK employer or agent to charge me for sponsorship?UK rules do not allow sponsors to pass on certain sponsorship costs, such as the immigration skills charge, to the worker, and recruitment agencies generally cannot charge work-seekers a fee for finding them work. You do pay your own official visa costs — the application fee, health surcharge, biometrics, TB test and any required English test — but you pay those to official channels, never into a personal account. Confirm current fees and rules on GOV.UK.
How can I tell if a certificate of sponsorship is genuine?A certificate of sponsorship is assigned electronically by a licensed sponsor and comes to you as a reference number you use in your visa application, not as a decorative PDF. Check that the employer appears on the Home Office register of licensed sponsors for the right visa route, and confirm the reference with the employer using contact details from its own website. If anyone asks for payment to "issue" or "release" a certificate, treat it as fraudulent.
An agent says they have a Home Office contact who can guarantee my visa. Should I pay?No. Visa decisions are made by the Home Office on the evidence in your application, and no employer, agent or "insider" can guarantee an outcome. Claims of special access are a standard fraud script. Pay only official fees through official channels.
I already sent my passport scan and NIN to a recruiter who now looks fake. What should I do?Assume the data may be misused. Contact your bank about monitoring or blocking, change passwords on accounts that use the same email, and keep all chats and payment records. Report the fraud to the Nigerian police and the EFCC, report the profile on the platform where you found it, and if a UK company or person is involved, report it to Action Fraud and through the immigration crime reporting page on GOV.UK.
