EDIT: Thank you all for the fast replies!

What I undestoood is that my parents can buy a visa on arrival for 2000 baht wchich allows them to stay in Thailand for 15 days. If we go to immigration office (close to the expiry day) with the purpose to extend, they will get a 7 day get out the country stamp for 1900 baht, thus denying the extension application, a total of 22 days in Thailand.

If we choose to apply for a tourist visa I need to aply for it in Germany, their country of residence. Please let me know if I summed it up correctly. Thank you.

Sawadika dear ones, my parents want to come and visit me with a Visa Upon Arrival- 14 days permitted to stay in Thailand.

My question is: ❔

once my parents are here can we go to immigration office and extend for another week-7 days for the standard 1900 baht?

Did anyone have experience with this?

Thank you very much for your help and tips. 🙏🌱

I am trying to avoid applying for a visa outside of Thailand.
