Is November 10th to January 24th enough time to get ED and Non-O Guardian visas for our move to Phuket?

We’re moving to Phuket and fly on 24 January 2027. Our two daughters will be attending an International School, we’re planning ED visas for the girls and a Non-O Guardian visa for each parent.

The school is starting their paperwork now. However, we’re attending a wedding in Spain and don’t return to the UK until 10 November. My understanding is that during the e-Visa application process we need to remain in the UK, which is why we’re planning to wait until we return from Spain before submitting the applications.

Do you think 10 November to 24 January gives us enough time to get all four visas approved?

Also, if for any reason they weren’t approved in time, is there a backup option that would still allow us to travel on 24 January and complete the process afterwards?

Thanks so much for any advice 😊
