I am trying to understand the process of converting visa-exempt stamps to ED and guardian visas.

Our child is eligible for an ED visa through her school. As I understand, once she arrives in Thailand on a visa-exempt stamp, we can apply for her to convert the stamp to a 90-day ED visa, and this 90-day ED visa can then be extended to a full year, correct?

If we do as above, and the parent arrives together with the child on a visa-exempt stamp, can the parent also apply for a guardian visa simultaneously with the child converting her visa exempt to an ED visa, or do we need to wait until we apply for the full-year extension for our child’s ED visa?

Looking forward to hear your guidance on this, as we have received ambiguous information.

We are based in Bangkok, in case that makes any difference.
