Hi everyone, I’m looking for some advice and assistance regarding a Thai visa process.

My boss is a US citizen who holds a Thai Permanent Residency (PR). He wants to sponsor his American parents to live with him in Thailand under a Non-O Visa. He has already prepared his legalized birth certificate, but we have two main concerns:

1 Mother’s Surname: His mother changed her last name to his father's after marriage. Will this cause any issues during the application?

2 Marriage Certificate: His parents got married in France. If a child with Thai PR is sponsoring their parents, is the parents' marriage certificate strictly required for the Non-O visa application?

Additional Question on French Documents:

If the French marriage certificate is indeed required and needs to be legalized, how can we request it?

We tried applying online, but the system requires a FrenchConnect account, which we don't have since we are not French citizens.

If anyone has experience with this or any helpful advice, please share. Thank you so much!
Summary so far
The user seeks advice on the Non-O Visa application process for their boss who is a Thai Permanent Resident sponsoring his American parents. Concerns include potential issues with the mother's surname, marriage certificate requirements from France, and how to legalize French documents for the application.
