Applying for a non o visa in my own country, (NZ) then on arrival will apply for a marriage visa. Question..is the marriage certificate in English acceptable at immigration or does it have to be translated to Thai .thankyou

Hello! I’m currently on visa amnesty until 29th January. I thought I was returning home but due to another flight being cancelled (getting back into Australia for residents is incredibly difficult at the moment I’m on my 10th cancelled flight) I’m looking into staying longer term and waiting it out to return. Does anyone know a reliable not dodgy visa agent? Thank you 🙏 I know it’s late notice but I’m hoping I can extend another 60 days under amnesty and then have my new visa organised.
