Do I need to cancel my extension of stay in Thailand in person before leaving?

You asked many questions...

Hi everyone. I am sorry if this question has been asked before. I have been living in Thailand since 2020, first with and Education Visa and then with extensions of stay based on marriage to a Thai national. Now I am on my second extension and with my wife we will be leaving Thailand in June.

***Does my extension need to be cancelled in person, or it will be automatically cancelled when I exit Thailand?

***It will cancel on departing Thailand.

Since we are returning to Thailand after March 2023 (the expiration date of my extension), getting a re-entry permit is not an option for me.

***In this case, can I come as a tourist and go from visa exemption (I hold a Chilean passport) to an extension of stay based on marriage

***YES you can enter as described.

***(or should I get the extension based on visiting family first to be able to do this)?

***That's an option when your Visa exempt or tourist visa ends...

I know I can also apply for a visa based on marriage in a Thai Consulate abroad.

***Does it need to be the Thai Consulate in my country of origin (Chile), or can it be in any country?

***Ask the Thai Consulate or Embassy in the country you are in ..

***Since this visa is granted, is there a standard period of time within which I must enter Thailand?

***Normally to be used within 3 months of its issue date.

But possibly up to One year if a Non O multi-entry Visa

**"And finally, is there a money requirement for this kind of visa (as there is to apply for the extension of stay based on marriage within Thailand)?

***Ask the Thai Embassy or Consulate where you are applying for the Visa.

Normally not...but is required in Thailand when you seek the Non O as Married to Thai.

I hope I made myself clear. Thanks in advance :)
