A work visa application is judged on its documents. A strong job offer can still fail if a certificate is missing, a name is spelled differently or a bank statement does not match the application. Every country has its own list, but many requests are similar. This guide gives a practical checklist for Nigerians, explains how to prepare each document and lists mistakes that cause delays.
Step One: Get the Official List
Start with the official checklist from the embassy, visa centre or immigration website of the destination country. Print it, tick each item and keep the date you checked. Lists change, and an agent’s old list can lead to a refusal. The guide below is a general base, not a replacement.
Identity Documents
| Document | Notes |
|---|---|
| International passport | Valid for the whole stay, usually with six months extra, with blank pages. Include copies of old passports if the embassy asks for travel history. |
| Passport photographs | Recent, with the size and background the embassy states |
| Birth certificate or declaration of age | Needed by some countries, especially for family applications |
| National Identification Number slip | Often asked for by Nigerian visa centres |
| Marriage certificate, if applying with a spouse | Original or certified copy |
Job Documents
- Signed job offer or contract showing job title, salary, hours, start date and employer details.
- The sponsorship document, such as a Certificate of Sponsorship, a job check approval, an LMIA or a work permit, depending on the country.
- Employer’s registration or licence details, if requested.
- Your CV, which must match your certificates and references exactly.
- Reference letters from previous employers on company letterhead, stating your role, duties and dates.
- Payslips or tax records that support your work history.
Education and Professional Documents
- Degree certificates and transcripts.
- NYSC discharge or exemption certificate, if the embassy asks for it.
- Professional registration or licence, for example nursing, engineering or teaching registration.
- Credential assessment or recognition decision, where the country requires one.
- Training certificates and trade tests for skilled workers.
Language Documents
- Test results from the approved test, such as IELTS or OET, with the test reference number.
- Proof of English-medium education, if the country accepts it.
- Check the validity date of the result.
Money Documents
- Bank statements, usually for three to six months, showing regular income and a normal history. Avoid large unexplained deposits just before applying.
- Proof of savings, a blocked account or a sponsor’s financial letter, if the visa needs it.
- Payment receipts for visa fees, health surcharges or other government charges.
Health and Character Documents
- Police clearance certificate, often from the Nigeria Police Force, with fingerprints taken as the process requires.
- Medical examination by an approved panel doctor, where required.
- Vaccination records or tests when the country asks.
- Health insurance proof, where required.
Accommodation and Travel
- Address in the destination country, or employer-provided housing details.
- Flight plans are usually not needed before the visa decision. Do not buy a ticket until the visa is issued unless the embassy says otherwise.
Translation, Certification and Legalisation
If a document is not in the language of the destination country or English, you may need a certified translation. Some countries also ask for an apostille or legalisation of certificates, which confirms that the signature or stamp is genuine. The requirement depends on the country. Ask the embassy which documents need which treatment, and do not stamp or alter documents yourself.
How To Organise Your File
- Create one folder with a subfolder for each category above.
- Scan every page in colour at a readable resolution. Name files clearly, for example “passport-bio-page.pdf”.
- Make a checklist spreadsheet with document, issue date, expiry date and where the original is.
- Keep a paper set in the same order as the embassy list.
- Back up the scans in two places.
Timeline
| Task | Suggested Time |
|---|---|
| Passport renewal, if needed | Start months before the application |
| Police clearance | Allow several weeks, then check how long the certificate stays valid |
| Credential assessment or recognition | Can take weeks or months |
| Language test | Book early and leave time for the result |
| Medical examination | Do it close to the application, because results expire |
Writing a Good Cover Letter and Explanation Letters
Some visa offices accept a short cover letter that guides the officer through your file. Keep it to one page. State who you are, which visa you apply for, the job and employer, and list the main documents attached. If something in your file may raise a question, such as a gap in employment, a name change or a large deposit, add a short, factual explanation with supporting proof. A plain, honest explanation helps more than a long story.
Biometrics and Appointments
Most work visas require fingerprints and a photo at a visa application centre. Book the appointment early, because slots in Lagos and Abuja can fill quickly. Bring the confirmation, your passport and the documents the centre lists. Dress simply, remove items that cover your face and arrive before your time. Pay fees only through the official payment page and keep the receipt. Never pay a stranger who claims to sell appointments.
Mistakes That Cause Refusals
- Different spellings or dates of birth across documents.
- Missing pages of a document, such as a transcript.
- Expired police certificates, medical reports or language tests.
- Reference letters that do not describe duties or dates.
- Bank statements with unexplained large deposits.
- Forged or altered documents. A single fake document can lead to a long ban, so never submit one.
- Using an agent who fills forms with incorrect information.
Frequently Asked Questions
Do I need original documents?
Some embassies want originals at the interview, and others accept scans. Follow the official instructions and keep originals safe.
What if a document is lost?
Ask the issuing office for a replacement or a certified copy and explain the situation in a short note if the embassy allows.
Can I fix an error after submission?
Sometimes, but not always. Contact the visa centre quickly and ask what is possible.
Should I pay an agent to prepare my file?
You can do the work yourself with the official list. If you use an adviser, choose one registered with the official regulator and never give them original documents without a receipt.
Final Thoughts
A clean, consistent set of documents is the best protection against delays and refusals. Start from the official list, collect slow documents first, check every name and date and keep copies of everything. Honest and complete files are processed faster.
