Spouse Visa: Handling Dependent Children’s Nationality, Schooling, and Health Insurance
Introduction

When applying for or renewing a spouse visa (such as Spouse or Child of a Japanese National or Spouse or Child of a Permanent Resident), if the household includes children, their personal circumstances are also reviewed as part of the screening.
In particular, factors such as whether the children are dependents, their nationality, schooling or nursery attendance, and enrollment in public health insurance are important indicators of family stability and actual living conditions.
This article explains how children’s information is handled in spouse visa procedures, and points to be aware of during screening.
👪 How Children Are Treated as “Dependents” in Spouse Visa Screening

If the applicant (the foreign spouse) has children, the immigration office will examine whether the children are supported as dependents, both under tax law and in daily life.
Being recognized as dependents demonstrates that they live together as a family and are financially supported.
| Category | Description | Example Documents |
|---|---|---|
| Tax dependents | Claimed as dependents in year-end adjustment or tax return | Withholding slip, tax return copy |
| Health insurance dependents | Covered as dependents under social insurance | Health insurance cards (insured and dependent) |
| Actual daily support | Living together, financial and educational support | Resident record, remittance records, school enrollment certificate |
- Even if not listed as tax dependents, children can still be regarded as dependents if they are actually being raised and supported.
- In cases of divorce or stepchildren, the immigration office will also confirm whether a legal parent–child relationship exists (through acknowledgment or adoption, etc.).
🌏 Children’s Nationality, Family Registry, and Residence Status

The required documents and how they are reviewed depend on whether the child holds Japanese or foreign nationality.
If the nationality differs, the office will check that birth registration, nationality acquisition, and residence status procedures were properly completed.
| Nationality | Key Checkpoints | Example Documents |
|---|---|---|
| Japanese (child of a Japanese parent) | Whether the child has acquired Japanese nationality | Family register, birth registration certificate |
| Foreign (child of two foreign parents) | Whether residence status procedures were completed after birth | Residence card, Certificate of Eligibility |
| Dual nationality | Whether both countries’ procedures were followed appropriately | Japanese family register + foreign passport, etc. |
- A child of a Japanese parent automatically acquires Japanese nationality, but if the birth registration has not been submitted, the child will not appear on the family register and must be added later.
- A foreign child must apply for a residence status within 30 days after birth (Immigration Control Act, Article 7).
🏫 School or Nursery Attendance and Family Stability

If the child is attending school or nursery regularly, it serves as proof of household stability.
This is especially valued positively in long-term stay or permanent residency applications.
| Point Checked in Screening | Example Documents |
|---|---|
| Whether enrolled | School enrollment certificate, nursery attendance certificate |
| Attendance and grades | Report cards, attendance records (optional) |
| Frequency of transfers | Resident record history, transfer documents between schools |
- If the family moves or changes schools frequently, the authorities may see the household as unstable. Attach a written explanation of the reason for moving if necessary.
- If a school-age child is not attending school, it may be viewed as a concern during screening.
🏥 Enrollment in Public Health Insurance

Enrollment in public health insurance is a basic indicator of household stability and dependent support.
If the head of household is a foreign national, it is important that all family members are enrolled in some form of public health insurance.
| Type | How It’s Evaluated | Example Documents |
|---|---|---|
| Social insurance (as dependents) | Seen as evidence of stable income and dependent support | Health insurance cards (insured and dependent) |
| National Health Insurance | Shows good faith even if income is lower | Insurance card, payment certificates |
| Not enrolled | Viewed as unstable and a major negative factor | — |
- When submitting copies of insurance cards, black out the personal ID numbers for privacy.
- If insurance premiums are unpaid, it may be seen as financial instability, which could negatively affect screening.
📋 Checklist of Documents to Prove Dependent Status

Below is a list of common child-related documents required in spouse visa applications.
Preparing them in advance will help the process go smoothly.
| Document | Purpose | Notes |
|---|---|---|
| Resident record (with relationship shown) | Proves household structure and cohabitation | Required, obtain one copy listing all members |
| Child’s family register or birth certificate | Proves nationality and parent–child relationship | Attach translation if foreign |
| Health insurance card (as dependent) | Proves dependent relationship and enrollment | Black out personal ID numbers |
| School or nursery enrollment certificate | Proves schooling or nursery attendance | Optional but useful |
| Remittance or household expense records | Proves financial support | Bankbook copies, money transfer records |
⚠️ Special Cases: Stepchildren or Children Living Separately

If a child is not living with the applicant or no legal parent–child relationship has been established, additional explanation is needed to avoid misunderstandings.
- For stepchildren, clearly state whether legal acknowledgment or adoption has been completed
- For children living separately, explain why they are not supported as dependents
- If supporting children from a previous marriage, submit evidence of ongoing support such as remittance records
- If the child lives overseas, add details about their local schooling and health insurance enrollment
When children do not live together with the applicant, immigration may mistakenly assume they are not being supported. Always attach documents to explain the relationship and actual support situation.
📌 Key Points and Summary

Here are the key points to keep in mind when submitting spouse visa applications involving children:
- Authorities check whether the children are treated as dependents
- Ensure nationality, family register, and residence status are properly in order
- School or nursery attendance shows household stability
- Enrollment in public health insurance is essential
- For special cases (stepchildren, children living separately), provide clear explanations and evidence
By preparing these properly, you can demonstrate a stable family environment and support structure, which will positively influence spouse visa screening.
If any of these elements are missing, immigration may see your household as unstable, which can negatively affect the outcome.
