The residence card for an expert’s child is one of the most underestimated dossiers — until the school asks for the student’s residence papers, or the child’s 18th birthday approaches. A child’s residence operates entirely on the family category, and every limit of that category must be calculated from day one.
The child’s residence structure: runs on the parents, clipped by the child passport
- Symbol: TT (family of a foreigner holding an LD/DT… card), ceiling 3 years under Article 38;
- Foundation: the expert parent’s valid residence card — the child’s card never outlasts its foundation;
- Passport clip: child passports in many countries run only 5 years, and the card always ends at least 30 days before the passport — families should renew the child’s passport before a long card application so the card term is not wastefully cut short.
The preparation point most often done wrong: relationship documents
The birth certificate is the central document and also the slowest, since it must be consular-legalized in the issuing country (or apostilled for Convention members from 11 September 2026) then notarized-translated. Common errors: using a non-notarized translation; the birth certificate spelling the parents’ names differently from the parents’ passports/residence cards (transliteration gaps must be explained with supporting documents); and preparing only one copy for the residence file while the school and insurers also need copies — legalize and notarized-translate several copies from the start.
Age 18: a category-conversion point to plan ahead
- 6–12 months before the 18th birthday: determine the next route (DH study at an educational institution in Vietnam / eligible employment / leaving Vietnam);
- If taking the DH route: contact the educational institution to build the study sponsorship dossier, converting the residence category in-country while the TT basis is still valid;
- Sync the derivative documents: insurance, school file, the child’s bank accounts when moving from the family category to an independent one.
The through-line principle: a child’s residence category never “self-extends” with schooling — each age phase has its own legal basis, and the family’s job is to bridge before the old basis expires.
A note for families with children on both sides of 18
When one child remains in TT and another has converted to an independent category, the family file splits into two separate chains with two different calendars. A company supporting the expert should keep a single family residence map (each member: category, expiry date, next conversion step) — most family overstay incidents come from the whole family sharing the parent card’s expiry milestone while each member’s card actually expires on different days.
Frequently Asked Questions
What is in the residence card dossier for an expert’s child?
A child under 18 of an expert falls in the TT family category. The card dossier under Article 37 of the Entry-Exit Law comprises: (1) the sponsoring organization/individual’s request (Form NA6) — in common practice the parent’s employer sponsors the whole family chain, or the parent sponsors personally; (2) Form NA8 with the child’s 2×3 photos; (3) the child’s passport; (4) proof of the relationship: the child’s birth certificate (or equivalent), consular-legalized/apostilled and notarized-translated into Vietnamese; (5) a copy of the expert parent’s residence card and residence documents at the family address. File at the immigration authority; processing takes 5 working days; the TT card runs up to 3 years, limited by the parent’s card and the child’s passport term (ending at least 30 days before the passport).
What happens to the family-based residence card when the child turns 18?
The TT category for a foreigner’s child applies only to children under 18 — at 18, the accompanying family basis ceases. The family must convert the child’s category before the 18th birthday: (1) if the child continues studying in Vietnam: convert to the DH study category (DH visa for persons entering to study; DH residence card up to 5 years) with sponsorship/dossier through the educational institution the child attends; (2) if the child works: the full labor route (work permit + LD category) as for any adult foreigner; (3) if no independent residence purpose remains: arrange exit when the TT basis ends. Leaving the child in Vietnam after the TT basis lapses is overstay — fined under Decree 282/2025/ND-CP and harmful to the child’s future residence files.
Does enrolling at a school in Vietnam itself create a residence right for the child?
Not automatically. Enrollment at an international school or a Vietnamese school is an education relationship, not a residence document: during the under-18 phase, the child’s residence runs on the TT family category via the parents — the school is not the residence sponsor for school students in this mechanism. The DH (study) category becomes a route only when the child studies at an educational institution eligible for study sponsorship and the dossier is made through that institution — the main option for the post-18 phase if the child continues to higher education in Vietnam. When planning a long study path (e.g. finishing school then university in Vietnam), the family should map the TT → DH conversion point from the beginning instead of handling it at the 18th birthday.
