Summary

Since 10 October 2025, Trinidad and Tobago has an express grandparent-based descent rule. The amended Constitution now covers a person born abroad where a parent or grandparent was a citizen at the time of birth (or would have been but for death), including a citizen by descent. Amended section 5(1) likewise provides a certificate process for a person born abroad whose parent or grandparent is a citizen, including by descent.

This materially expands the former rule. It can reach a person born outside Trinidad and Tobago who relies directly on a citizen grandparent, rather than requiring the intervening parent to have citizenship “otherwise than by descent.”

Eligibility

The applicant should be able to prove:

For an applicant under 18, the prescribed section 5 application may be made by the responsible parent, guardian, or grandparent. An applicant who has attained full age may apply personally. The 2025 replacement of section 5(1) removed the former requirement to apply within one year after reaching majority.

The 2025 Act replaced section 5(1) but did not expressly replace section 5(2), which contains older wording restricting further transmission through a person who received a section 5 certificate. The public Chapter 1:50 consolidation also predates the amendment. Because the newer constitutional text expressly includes grandparents and citizens by descent, this textual tension should be confirmed with the Immigration Division in unusual multi-generation cases.

What This Route Allows

A person within amended section 17(3) is a citizen by descent. The section 5 certificate or a Certificate of Immigration Status can document the claim, after which the person may apply separately for a Trinidad and Tobago passport.

Section 11(2D) says a citizen by birth or descent does not lose Trinidad and Tobago citizenship merely by acquiring another citizenship. The other country's nationality law must still be checked.

What This Route Is Not

This is not an unlimited ancestry route. The amendment identifies a parent or grandparent, not a great-grandparent or any more distant ancestor. The applicant must prove every civil-record link and the grandparent's citizenship.

It is not accurate to apply the old one-generation-only rule or the old one-year adult application deadline after 10 October 2025. It is also not safe to assume that an old passport checklist resolves every conflict in a complex chain.

Next Steps

  1. Build the complete applicant-parent-grandparent record chain with full birth certificates and marriage/name-change documents.
  2. Prove how and when the grandparent became a citizen of Trinidad and Tobago.
  3. Keep copies of the 2025 amending Act and commencement Proclamation with the case, because older consolidations remain online.
  4. Ask the Immigration Division which certificate/status procedure and form it currently uses for a direct grandparent claim.
  5. Confirm current apostille, translation, fee, and first-passport requirements before submitting original foreign records.
