One of the questions I hear most often from families arriving in Phuket: "My kids — do they just travel on my visa?" The short answer is no. Every person entering Thailand — including newborns — needs their own entry status. But the good news is that the Thai immigration system is reasonably family-friendly once you understand how it works.
Whether you're moving to Phuket with school-age kids, expecting a baby while living here, or your teenager is approaching 18 and needs to transition off your dependent status, this guide covers the mechanics in plain language.
All visa extensions and dependent status matters in Phuket are handled at the Chalong Immigration Office (the main office near the overpass, open Mon–Fri 08:30–16:30). There's no longer a satellite office in Patong for extensions.
Do Children Need Their Own Visa?
Yes — unambiguously. A Thai visa or entry stamp is issued per passport, not per family unit. Even a three-month-old infant needs their own passport and their own Thai entry stamp or visa.
In practice, this means when you arrive at Phuket International Airport, every member of your family goes through passport control individually (or at the family lane, but each passport is processed separately). Children holding a foreign passport from a visa-exempt country get a tourist entry stamp, same as an adult.
Where it gets more nuanced is when you're staying long-term. Children can be placed on a "dependent" status linked to a parent's long-stay visa — but they still have their own entry in the system, their own stamp in their passport, and their own 90-day reporting obligations.
How Dependent Status Works
If you hold a long-stay visa in Thailand — Non-OA (retirement), Non-O (family/marriage), Non-B (business), Non-ED (student), or an LTR — your minor children can be granted dependent status that mirrors your visa validity.
The terminology Thai immigration uses is "Non-O dependent" — even if your main visa is a Non-B or LTR, the dependent child typically receives a Non-O stamp referencing "accompanying spouse/child." This is standard practice and nothing to worry about.
What dependent status gives your child
- Permission to stay in Thailand with the same validity as your main visa (typically 1 year, extendable)
- Multiple re-entry if you add a multiple re-entry permit (฿3,800 per person — worth it)
- Legal status for school enrollment
- Freedom from needing to do border runs
What it does NOT do
- It does not grant work rights (children typically don't need these anyway)
- It does not mean the child can stay if the sponsoring parent leaves Thailand permanently
- It expires when you turn 18 — more on that below
If you're applying for your own extension of stay at Chalong, bring your children with you (or their passports, if they can't come). The immigration officer will process both the parent extension and dependent extensions in the same sitting. Bring passport-size photos for each child — they always ask.
Documents Required for a Child's Dependent Visa
The exact document list varies slightly depending on your main visa type, but for most families the list is:
| Document | Notes |
|---|---|
| Child's original passport + photocopy | Must be valid for at least 12 months beyond the requested stay |
| Parent's original passport + photocopy | Including all pages showing current visa and extensions |
| Child's birth certificate | Original + certified copy. If not in English or Thai, you'll need a notarised translation |
| Parent's proof of relationship | Birth certificate naming parent, or marriage certificate if using spouse's visa |
| Parent's residence certificate | From your local Amphoe or Tessaban; or a rental contract showing address |
| TM.7 form | Extension of stay application — one per family member |
| Passport photos (4×6 cm) | Two per person, taken within 6 months |
| Extension fee | ฿1,900 per person per extension |
If your child was born in Thailand and has a Thai birth certificate, it's worth keeping both an original and several certified copies. The birth certificate from the local Amphoe is your proof of the parent-child relationship for Thai immigration purposes.
Babies Born in Phuket
If you're expecting while living in Phuket, here's the process for getting your newborn legal status in Thailand.
Birth Certificate from Hospital
Bangkok Hospital Phuket and Siriroj Hospital both issue Thai birth certificates (ใบสูติบัตร) within a few days of birth. Register at the local Amphoe too.
Home Country Passport
Apply through your embassy or consulate — most allow postal applications from Thailand. UK parents use the online HMPO system; US parents through the Embassy in Bangkok.
Thai Visa or Entry Stamp
Once the baby has a passport, they need Thai status. Take them to Chalong immigration for a dependent Non-O linked to your visa. The baby needs their own TM.7 form.
90-Day Reporting
Yes — even newborns. Set up the 90-day reporting online account using the baby's passport details and report at the same time as yourself.
Until the baby has a home-country passport, they're in a legal grey area. If you're close to your due date, have your passport in hand before delivery if possible, and factor in 4–8 weeks for home country passport processing.
Thailand is not a jus soli country. A baby born in Phuket to two foreign parents is NOT Thai. They will require a foreign passport and a Thai visa or dependent status. The only exception: if one parent is Thai, the child typically qualifies for Thai citizenship through that parent's nationality (jus sanguinis).
Children and School Enrollment in Phuket
International schools in Phuket — BISP in Bang Tao, UWC Thailand in Phuket Town, and HeadStart in Kathu — all accept children regardless of visa type. However, the school itself will typically push you to get a Non-ED (student) visa or ensure the child has a valid long-stay status.
Non-ED visa for school-age children
A Non-ED ("Education") visa allows a child to stay in Thailand specifically for the purpose of studying. For children enrolled at an international school, the school acts as the sponsor.
- How obtained: The school applies to the Ministry of Education on the child's behalf; you then take the approval letter to a Thai consulate (Kuala Lumpur and Penang are popular from Phuket)
- Duration: Typically 1-year stamps, renewable annually
- Cost: ฿2,000 per year for extension at immigration; plus visa fee at consulate (~฿1,000-2,000 depending on country)
- 90-day reporting: Still required
For most families, if you hold a valid long-stay visa yourself (Non-O, Non-B, retirement, LTR), it's simpler to put the kids on your dependent status rather than obtaining separate Non-ED visas. Discuss with your school which route works better for your situation.
See our Phuket international schools guide for more on the enrollment process at BISP, UWC, and HeadStart, including fee structures and waiting lists.
90-Day Reporting for Children
Every foreign national staying in Thailand for more than 90 consecutive days must file a 90-day report — including children. This catches many new expat parents off guard.
The easiest solution: create an account on the immigration.go.th website for each child's passport, and link the 90-day notification dates to your phone calendar. You can report online up to 15 days before and 7 days after the due date.
In Phuket, if you miss the online window, you report in person at Chalong Immigration. There's a fine of ฿2,000 for late reporting, applied per person. If you're away from Thailand on the due date, the clock resets on your return — keep track of your children's individual dates separately from your own.
Many families I know sync all family members' 90-day dates by doing a short border run together, which resets everyone's clock simultaneously. After that, everyone reports on the same day each quarter. Makes it much simpler to manage.
When Your Child Turns 18
At 18, a dependent child loses their dependent immigration status. This is a transition that sneaks up on families — plan for it at least 6 months in advance.
Options for an 18-year-old who wants to remain in Phuket:
| Situation | Recommended Visa | Notes |
|---|---|---|
| Still in school (e.g., A-levels, IB Year 2) | Non-ED (student) | School sponsors; must enroll full-time |
| Taking a gap year / not working | Tourist visa + extensions | Doable but border runs or visa runs required every 60-90 days |
| Working remotely / digital nomad | DTV (Destination Thailand Visa) | 5-year multiple entry, 180 days per stay; ฿10,000 fee; requires proof of income |
| Planning to work for Thai employer | Non-B (business) | Employer must sponsor; requires work permit |
| University in Thailand | Non-ED via university | Chiang Mai, Bangkok, or Phuket campus programs available |
The DTV (Destination Thailand Visa) has become the go-to for young digital nomads aged 18–25 who can show freelance or remote income. It requires a ฿500,000 (~USD 14,000) bank statement or equivalent, which is manageable if they're already earning.
Don't leave this until the last minute. Getting a new visa category organised can take 6–8 weeks if you need to apply through a consulate abroad. A good Phuket visa agent can walk you through the transition.
Sole Parents and Single-Custody Situations
If you're a single parent, or if the other parent is not in Thailand, you may face extra scrutiny at Phuket Airport when travelling with a child — particularly if you and the child have different surnames or nationalities.
Practical steps to reduce the chance of problems:
- Carry a copy of your custody order, or a notarised letter from the other parent granting permission to travel
- If you have different surnames, carry the child's birth certificate linking you to them
- Some countries issue "child travel documents" noting single-parent custody — useful to have
- This is rarely an issue at Phuket Airport in practice, but it does come up occasionally, especially on international departures
Working With a Visa Agent for Family Immigration
Family immigration paperwork is one of the areas where a Phuket visa agent earns their fee. Between the parent's extension, dependent children's extensions, 90-day reports, and re-entry permits — all filed on different dates — there's a lot to track.
A reputable agent in Phuket charges around ฿3,000–5,000 per extension (on top of the ฿1,900 immigration fee) and will often handle the whole family's paperwork as a package. They know which documents Chalong immigration officers want, which forms have changed, and how to handle edge cases like child custody situations or different nationalities within a family.
