The father is an EU member national, and his daughter holds dual nationality (Thai/EU nationality). If applying for the NON O guardian visa based on a Thai child is not an option, the alternative would be the NON O guardian visa based on a non Thai child, that is, through her ED visa as a student at an international school, with the father attached to her visa as her guardian.

My question is: would the father be eligible to pursue this second option?

For instance, by submitting the child’s EU birth certificate and her EU passport at the local immigration for the extension?

Please note, I am not seeking advice on the first option (guardian of a Thai child), so I kindly ask that responses focus solely on the alternative route.

Additional context:

• The child is 10 years old

• She was born in Thailand

• She holds both Thai and EU passports

I do bear in mind that, different immigration offices exercise discretion differently.

Thank you in advance for your input and for sharing any similar experiences.
