How to Write a Letter of Invitation for a Nigerian Visa

The letter of invitation is the document the Nigeria Immigration Service reads most carefully. It tells the officer who is coming, why, for how long, who is responsible for them and what they will actually do. Weak letters are one of the most common reasons applications stall.

What the Letter Must Establish

• Who the sponsor is, with registered name, RC number, address and contact details.
• Who the traveller is, with full name exactly as it appears in the passport, nationality, passport number and date of birth.
• Why this person is needed — the project, the equipment, the vessel, the client, and the specific expertise being brought in.
• What they will do, described in terms that match the visa category applied for.
• How long they will stay, with arrival and departure dates.
• An explicit acceptance of immigration responsibility for the traveller during the stay.

Wording That Causes Problems

Vague purpose statements — "for business discussions" with no further detail — give the officer nothing to approve. So does language that contradicts the category: a business visa application whose invitation letter describes installation, commissioning or repair work is a contradiction on the face of the file. Write the activity accurately, then apply for the category that matches it.

A Structure That Works

1. Sponsor letterhead with registered details.
2. Addressed to the Comptroller General, Nigeria Immigration Service.
3. Subject line naming the visa category and the traveller.
4. Paragraph one: who the sponsor is and what it does, with sector registrations where relevant.
5. Paragraph two: the project, the client and the technical need.
6. Paragraph three: the traveller, their role and their credentials.
7. Paragraph four: dates, location and accommodation.
8. Paragraph five: acceptance of immigration responsibility.
9. Signature by an authorised officer with name, position and contact number.

Supporting Documents

The letter is stronger when it references and travels with the underlying evidence: the contract or purchase order, the vessel or project details, the traveller's credentials and the sponsor's corporate and sector registrations.

Common Failures

• Passport name spelled differently in the letter.
• Dates that conflict with the flight itinerary.
• A signatory whose position is not stated or who cannot be reached.
• A letter that reads as a template with the project details left generic.

How PeaceRyde Helps

PeaceRyde drafts and issues letters of invitation as a Nigerian incorporated sponsor, aligns them to the correct visa category and the supporting evidence, and files the application with the Nigeria Immigration Service.

Key Takeaways

• The invitation letter is the document NIS reads most carefully.
• It must name the sponsor, the traveller, the specific need, the dates and accept responsibility.
• Vague purpose statements and category contradictions are the main failure points.
• Names, dates and job titles must match the passport and the itinerary exactly.
• A signatory with a stated position and reachable contact number matters.

Frequently Asked Questions

Can the traveller write their own invitation letter?

No. The letter comes from the Nigerian sponsor, on its letterhead, signed by an authorised officer who accepts immigration responsibility.

How detailed should the purpose be?

Detailed enough that an officer understands the project, the client, the technical need and why this particular person is required. Generic wording is a common cause of delay.

Does the letter need supporting documents?

It is far stronger with them — contract or purchase order, vessel or project details, traveller credentials and the sponsor's corporate and sector registrations.
