My wife has had had an extension of stay based on being a guardian of our daughter studying at an international school in Bangkok. Both need to renew their extension of stay in a few weeks at CW. How easy is it to change her next extension of stay from Guardian to retirement (she is now 50 and complies with all the requirement). Is it just a matter of filling in the new reason on the application form and go to the queue for retirement or is it more involved?

No problem for her to apply for an extension of stay based upon retirement as long as she meets the financial requirements for it.

Just put the new reason on the TM7 application form.

Dear Ubonjoe,

 

Unfortunately not as easy as you (and I) would have thought.

 

We did as you suggested but were told by CW Immigration that my wife first had to cancel her "Guardian" extension of stay. For this we need a letter from my daughter school which we did not have with us of course.  Turns out that my daughter school is indeed familiar with this procedure and can provide us with the cancellation letter. However the school also warned us that cancelling the "Guardian" extension of stay may take up to two weeks and there is no guarantee that once cancelled my wife may or may not be approved for extension of stay based on retirement.

 

The school acknowledged that they are not so familiar with extension of stay based on retirement so would appreciate your opinion or any other TV member of his experience in this matter.

Nonsense

Immigration will cancel the extension as soon as her application is presented with the cancelation letter attached.

That means we should be able to apply for retirement extension of stay on the same day? First cancel guardian extension at the "education visa counter" and then proceed with a new queue number and apply for retirement extension of stay.

Yes you can do it on the same day. You may not need 2 queue numbers. The retirement extension desk should be able to do the cancellation.
