01Who qualifies

Who qualifies, generation by generation

LIKELY

Can you claim Trinidadian citizenship through a parent?

Citizen by descent

A child born abroad to a Trinidad and Tobago citizen is a citizen by descent and proves it with a first passport application.

POSSIBLE

Can you claim Trinidadian citizenship through a grandparent?

Citizen by descent

Grandchildren of Trinidad and Tobago citizens are citizens by descent since the 2025 amendment, if born on or after 1 August 1976.

What would settle itYour date of birth: the grandparent route applies only from 1 August 1976.

What changes the answer

  • UNLIKELY
    If you were born before 1976Two generations

    The grandparent route does not reach grandchildren born before 1 August 1976; if your parent is a citizen, you may still qualify as a citizen's child.

  • LIKELY
    If you were born in 1977 or later

    Since the 2025 amendment, a grandchild of a Trinidad and Tobago citizen is a citizen by descent and proves it with a first passport application.

  • UNLIKELY
    If the grandparent is your grandmother and you were born before 1976Two generations

    The grandparent route does not reach grandchildren born before 1 August 1976; if your parent is a citizen, you may still qualify as a citizen's child.

  • LIKELY
    If the grandparent is your grandmother and you were born in 1977 or later

    Since the 2025 amendment, a grandchild of a Trinidad and Tobago citizen is a citizen by descent and proves it with a first passport application.

UNLIKELY

Can you claim Trinidadian citizenship through a great-grandparent?

Two generations

The 2025 amendment reaches children and grandchildren of citizens, not great-grandchildren; a parent who becomes a citizen through your great-grandparent's child makes you a citizen's grandchild.

What would settle itWhether a living parent or grandparent can become a citizen first.

02Dates that matter

The dates that matter

  1. 1976
    1 August 1976

    The Government applies the amendment: consulates issue first passports “by descent (through grandparents)”, which does not apply to grandchildren born before 1 August 1976, and the grandparent must have been a citizen when the applicant was born. Consulate General of Trinidad and Tobago, New York: first-issue adult passport instructions (January 2026)

03Mothers’ lines

How mothers’ lines were treated

In Trinidad and Tobago’s rule, the answer changes when the line runs through a woman:

  • UNLIKELY
    If the grandparent is your grandmother and you were born before 1976Two generations

    The grandparent route does not reach grandchildren born before 1 August 1976; if your parent is a citizen, you may still qualify as a citizen's child.

  • LIKELY
    If the grandparent is your grandmother and you were born in 1977 or later

    Since the 2025 amendment, a grandchild of a Trinidad and Tobago citizen is a citizen by descent and proves it with a first passport application.

04Keeping your citizenship

Dual citizenship with your home country

You keep your citizenship.

On every open route, the rule lets a citizen of the United States, Canada, the United Kingdom, Australia, New Zealand, Brazil, Argentina or South Africa keep that citizenship.

05The routes

Every route, and the law behind it

  • LIKELY
    Through a parent
  • POSSIBLE
    Through a grandparent
  • LIKELY

The law

What would settle an unsure case

  • Your date of birth: the grandparent route applies only from 1 August 1976.

Two generations

Closed: no open answer on this route

  • UNLIKELY
    Through a grandparent, if you were born before 1976

    The grandparent route does not reach grandchildren born before 1 August 1976; if your parent is a citizen, you may still qualify as a citizen's child.

  • UNLIKELY
    Through a great-grandparent

    The 2025 amendment reaches children and grandchildren of citizens, not great-grandchildren; a parent who becomes a citizen through your great-grandparent's child makes you a citizen's grandchild.

The law

What would settle an unsure case

  • Whether your parent was a citizen when you were born, which makes you a citizen's child rather than a grandchild.
  • Whether a living parent or grandparent can become a citizen first.

06The documents

The documents, as the rule lists them

Citizen by descent

Through a parent

  • Your parent’s Trinidad and Tobago birth certificate or passport
  • Your birth certificate
  • The first-issue passport application

Through a grandparent

  • Your grandparent’s computerized Trinidad and Tobago birth certificate or passport, and any foreign naturalization certificate
  • Your parent’s birth certificate
  • Your birth certificate
  • The first-issue passport application

Most countries also want proof that no one in the line became a citizen elsewhere before the next birth: the naturalization record with its date, or a letter that none exists.

07What it takes

What it takes: time, cost, the hard part, who decides

Citizen by descent

Time
Unpublished for the new grandparent cases; consulates review the posted file, then interview. Budget 6–18 months.
Cost
About $300–700: the $126 first-passport fee through the New York consulate (January 2026 chart), apostilled U.S. records and copies.
The hard part
Proving the chain on the first passport application: a grandparent who was a citizen when you were born, and a birth on or after 1 August 1976, when the grandparent route begins.
Who decides
The Immigration Division, through the Trinidad and Tobago consulate for your U.S. address, by post, followed by an interview.
The first record
Your parent’s or grandparent’s Trinidad and Tobago birth certificate or citizenship certificate, from The Registrar General. Order the certified copy through the Registrar General’s online application service or by mail with the name, birthdate and district; a few weeks. rgd.legalaffairs.gov.tt

How it’s filed

Where
By post to the Consulate General of Trinidad and Tobago for the member's address (New York, Miami or Washington). office list
How
By post; you appear in person
Appointments
The consulate invites you to an interview once the posted file is reviewed. No self-service booking from the U.S.; appointments.gov.tt is for passport offices in Trinidad and Tobago.
Fee
About $126
Decision
1–6 months
What goes in the file (8)
  1. The completed first-time MRP application form (section 4 left blank until the interview)
  2. Your birth certificate or certificate of live birth, apostilled
  3. Valid identification from your country of birth (e.g. passport)
  4. Marriage certificates, divorce decrees and any name-change documents, apostilled, if applicable
  5. Through a parent: proof of the parent's T&T citizenship at the time of your birth (their computerized birth certificate, T&T passport, marriage certificate, name-change documents) and their foreign naturalization certificate if any
  6. Through a grandparent: your parent's birth certificate, passport and marriage/name-change documents, plus the grandparent's computerized T&T birth certificate or passport and their foreign naturalization certificate if any (grandparent documents may be waived if your parent already holds a T&T MRP)
  7. Coloured copies of everything by post; originals at the interview
  8. A money order or cashier's check for $126 payable to the Consulate General of Trinidad and Tobago
What goes wrong (9)
  • Grandparent route: 'does not apply to grandchildren born prior to August 1st 1976', and the grandparent must have been a T&T citizen at the time of your birth (Consulate General New York, January 2026).
  • A grandparent (or parent) who naturalized elsewhere before dual citizenship was allowed in 1988 may have lost T&T citizenship before your birth; the consulate asks for their foreign naturalization certificate to check the date.
  • All documents not issued in Trinidad and Tobago must be apostilled.
  • Fee: $76 passport + $20 diplomatic service charge + postage = $126 (32 pages, ages 2–59); $156 for 48 pages; $50 for 60 and over (effective 22 January 2026).
  • USPS no longer sells international money orders; MoneyGram, Western Union or a cashier's check.
  • The Citizenship Act regulations (Legal Notice 490 of 2025, in force 1 January 2026) doubled citizenship fees; a separate Certificate of T&T Citizenship costs $23 with a passport application at the consulate.
  • Unverified: decision time at the consulate; domestic standard processing is 4 weeks.
  • From CA: the High Commission in Ottawa (and consulate in Toronto) handles the same application in CAD. From GB: the High Commission in London. Unverified fees.
  • Miami and Washington addresses (above) were previously unlisted; only Miami's email (consulatemiami@foreign.gov.tt) and Washington's address were found on a government-adjacent domain (foreign.gov.tt), not independently re-verified per office this pass.

    Good to know (4)
    • The passport office wants the COMPUTER-GENERATED birth certificate with a PIN, not an old handwritten copy.
    • Unverified start year: Trinidad civil birth registration is generally dated from 1848, Tobago later.
    • The RGD site serves an incomplete TLS chain to automated clients (curl -k works); fee unverified.
    • RGD's Port of Spain postal address above was found by search 2026-09-25. Whether a descendant abroad (not the citizen themselves) may request the RGD birth certificate directly is unconfirmed.
