Thank you

Guess: You have a used and expired visa in your passport. You went to Immigration and got a new stamp with the text: Extension of Stay permitted up to 30 Apr 2023.

This Extension of Stay needs to be cancelled on your last day of working at the company who provided the documents, you may apply for a new Extension of Stay and get 7 days to leave the country.

It is YOUR passport and YOUR work permit. YOU have to take action and not wait if your employer has time.

You can cancel both in advance, as example visit Ministry of Labor on 15 July and cancel your work permit on 1 Aug as last day of working, then visit the Immigration Office and do the same. There is always time enough, if you do not wait until boarding the plane.

as you move into a new place you have to report that within 24 hours, just ask directly how and when you have to report if you travel around due to business and come back to the same address.

Thank you all for the contributions but the OP has the answer he needed.

You take both passports and show them to the Immigration on return in Thailand. You get stamped into your new passport. To transfer the stamps you need to visit your local immigration office after return. The Thai Embassy does not provide this service.

Talk to the hospital staff and get a letter that she is unable to travel based on medical reasons, with that letter and her passport you can apply in her name for the Extension of Stay, with a maximum of 90 days at the time.

Hope she get well soon.

Yes and that is based on working in Thailand which you are not allowed to do for a week as your Work Permit is expired, you need to organize quickly a new work permit or cancel this stay based on working.

It must be a big stamp like this example but with the date 15 sep 2022.

I deleted your picture as your passport number was visible

So if you look into your passport, you will see a big stamp with in line 2: Extension of Stay permitted up to xx/xx/xx
