5 Common Mistakes That Delay UK Visa Decisions (And How Nigerian Nurses Can Avoid Them)
You’ve done the hard work – job offer, NMC registration, savings in place. You submit your visa application and wait.
Then weeks pass. Then months. Sometimes, the decision doesn’t come – or worse, it’s a refusal.
I’ve analyzed dozens of visa applications from Nigerian nurses, and certain mistakes appear again and again. The good news: every single one is avoidable. Here are the top five, and how to steer clear.
❌ 1. Failing the 28-Day Proof of Funds Rule
UK Visas and Immigration requires you to show you have at least £1,270 (approx. ₦1.3 million) in your bank account for 28 consecutive days, ending no more than 31 days before your application date.
The mistake: Using an account where funds drop below the threshold even for one day, or using statements that don’t cover the full 28-day period.
How to avoid:
• Open a dedicated savings account and transfer the required amount.
• Leave it untouched for at least 28 days.
• Download bank statements showing every day of that period.
• If using a sponsor’s account, include a letter of support and proof of relationship.
❌ 2. Submitting an Incomplete Document Set
Missing even one required document can lead to a delay or outright refusal. Common omissions:
• TB test certificate (must be from an approved clinic)
• Police character certificate (required for NMC, but sometimes overlooked for visa)
• English language certificate that has expired
• Birth certificate or sworn affidavit
How to avoid:
Use a checklist. I’ve compiled a 47-item document checklist that covers every single piece of paper you need – personal, professional, financial, and medical. Go through it line by line before submitting.
❌ 3. Using an Unapproved TB Test Clinic
The UK only accepts TB test results from clinics it has approved. In Nigeria, the approved clinics are in Lagos, Abuja, and sometimes other cities. Using a clinic not on the list means automatic refusal.
How to avoid:
Check the current list on the UK government website (check our previous articles) before booking. Stick to names like IOM (International Organization for Migration) or other listed providers. Keep the certificate – it must be uploaded with your application.
❌ 4. Inconsistent Information Across Documents
Your name, date of birth, and passport number must match perfectly across your passport, bank statements, TB certificate, and other documents. Even a minor discrepancy (e.g., “Oluwaseun” vs “Oluwaseun Temitope”) can raise red flags.
How to avoid:
Use exactly the same name as on your passport for all applications. If documents show a different name (e.g., marriage certificate), include an affidavit explaining the difference.
❌ 5. Applying Too Early or Too Late
• Too early: You cannot apply more than three months before your Certificate of Sponsorship (CoS) start date.
• Too late: If your CoS expires before you apply, you’ll need a new one from your employer.
How to avoid:
Track your CoS start date and expiry date. Set reminders to apply within the window. If you’re waiting for NMC registration, communicate with your employer to ensure your CoS dates are adjusted.
✅ The Big Picture
Each of these mistakes adds weeks or months to your journey – and some can derail it entirely. But with careful preparation, you can avoid them all.
I’ve put together a detailed step-by-step resource that walks you through every stage of the Health and Care Worker visa process, including document checklists, savings trackers, and timelines tailored for Nigerian applicants. It’s designed to help you stay organised and avoid the delays that catch so many nurses off guard.
If you’d like to take the guesswork out of your application, you can find that resource in my profile or send me a message for details.
