Applying for a family visit visa—whether for Japan, Europe, the U.S., or other countries—the most crucial step is to prove your relationship with the family member living abroad. If the relationship cannot be clearly verified, the chances of visa rejection are very high.

Relationship Documents

• Birth Certificate – To prove parent–child or sibling relationship
• Household Registration – To show that family members live under the same household
• Marriage Certificate – For spouses
• Photos Together – Strong supporting evidence, such as photos taken on various occasions

Documents from the Inviter (Sponsor / Guarantor)

• Invitation Letter – Stating the relationship and the reason for the invitation
• Copy of Passport (or Resident Card) of the inviter
• Proof of Legal Residence – For example, entry stamps to Thailand or residence permit in the host country
• Financial Evidence – Bank statements or salary slips showing the inviter’s financial capacity
• Letter of Guarantee – If available, this strengthens the application

Key Summary

• The more complete and consistent the documents, the higher the chance of visa approval

• Clear proof of relationship – Supported by official documents

• Valid status of the inviter – Passport, residence permit, financial capacity
