What are my options after leaving the UK while my Thai visa application is pending?

Seeing as you cannot follow written instructions I will not be surprised if your visa is rejected outright.

Just send an E-mail to the Embassy.

Your visa to stay in the UK ended and that they should not ask anything.

Demand your visa based on FAcebook comments.

Demand they do their work and they have to let you visit Thailand to spend hundreds of millions Thai baht, pay taxes so their salary is guaranteed.

Enjoy your time in Germany and dream on.

This is the 5 time this person ask the same question as he did not get the advice he likes.

Now he has the advice he loves to read.

The rules are pretty clear. You need to reside in the country you're applying from and wait. Maybe I'm wrong but I think that's a hard and fast rule.

This does seem like a typo from the embassy ie the refundable part!

The Royal Thai Embassy, London website states:

"It is important to note that the visa fee is non-refundable and non-transferable. The visa fee is also subject to change without prior notice."

This embassy is extremely considerate! Refund, wow!I hope that's not a typo😉!

Get back in UK and complete your application 🤦🏻‍♂️. Mistakes happen. Set it right now.

You're lucky in that they appear to be offering to refund your application fee for the UK. You have 2 choices.

Either return to the UK, and then provide the letter stating you will remain there until the process completes along with the other information OR get a refund from the UK and make a new application using the consulate that serves your current location and remain there until the process completes

If you want to continue with your current application, you need to immediately return to the UK, as you were not supposed to leave. You need to send a letter confirming that you are in the UK and won’t leave and an updated flight from the UK to Thailand. otherwise, you can have them cancel your application and you can re-apply in the country where you are now, starting all over.

They specify in the application that you are supposed to apply from the country you are in and remain there until the application has been processed and completed to approval or rejection.

Seeing that you have now left the UK your options are to either return back to the UK, provide the requested documents and a flight from the UK to Thailand. Alternatively, you can cancel the current application and start a brand new one from the country you are currently in, but will need to remain there until the application is complete and processed through to acceptance or rejection.

You must remain within the country/jurisdiction of the Embassy you applied to for the duration of the application.
