Immigration DNA testing in Nigeria has become an essential part of many visa, citizenship, and family reunification applications. Whether you're trying to bring a child abroad, reunite with a sibling, or prove biological ties for immigration purposes, DNA testing offers scientific clarity—and in many cases, it’s a legal requirement.

In this guide, we break down everything you need to know about immigration DNA testing in Nigeria: from why it's needed, to what documents you'll need, the types of tests available, what to expect at your appointment, and how long results take.

Why You Might Need a Legal DNA Test for Immigration

Immigration authorities may request a DNA test when there is insufficient documentary evidence to prove a biological relationship. Some common legal reasons for DNA testing under immigration cases include:

Visa applications - DNA testing may be required during visa applications to confirm biological relationships when supporting documents are missing or questioned.
Family reunification - In family reunification cases, DNA testing helps prove blood relationships between applicants and sponsors, such as parent-child or sibling ties.
Citizenship claims - DNA testing is often used to support citizenship claims by verifying that the applicant is biologically related to a citizen parent or grandparent.
Paternity or Maternity Proof – To confirm biological parent-child relationships
Sibling Testing – When claiming a brother or sister as part of a visa or citizenship petition
Grandparent Testing – When the parents are unavailable or deceased
Family Reunification Cases – For dependent children, spouses, or extended family
Adoption or Guardianship Confirmation – To validate a claimed relationship in family-based immigration
Refugee and Asylum Claims – In situations where documentation has been lost or is unverifiable
Immigration Appeals – When a visa application has been rejected due to doubts around family ties
Surrogacy - In order to obtain foreign citizenship for your child and parental orders

These tests are typically requested by embassies, immigration lawyers, or government agencies like the UK Home Office, USCIS, or Canadian IRCC.

Documentation Required for a DNA Test

To take a legal DNA test for immigration purposes in Nigeria, you’ll need to provide:

Valid Government-issued ID (e.g., international passport, national ID, NIN slip)
Embassy or immigration letter requesting DNA testing (if applicable)
Birth certificates or other proof of claimed relationship (where available)
Passport photographs (for official documentation and ID matching)
Completed consent forms (especially if minors are involved)

⚠️ Important: The test must follow a strict chain-of-custody procedure, meaning it must be witnessed and properly documented to be legally valid.

Types of DNA Tests & Their Specific Requirements

Depending on your immigration case, you may need one of the following DNA tests:

1. Paternity Test

To confirm a biological relationship between a father and child.

Requirements: Both father and child must be present or submit samples through approved channels.

2. Maternity Test

To prove a biological relationship between a mother and child.

Requirements: Same as above, with mother and child involved.

3. Sibling Test

Used when no parent is available, and siblings need to prove biological connection.

Requirements: Both siblings submit samples; additional family members may strengthen the result.

4. Grandparentage Test

To determine if grandparents are biologically related to a grandchild.

Requirements: Ideally includes both grandparents and the child. Can be complex, and often requires supporting documentation.

5. Avuncular Test (Aunt/Uncle)

To verify whether a child is biologically related to a sibling of the parent.

Requirements: DNA samples from the child and the alleged relative.
