My daughter is at international school and I am obtaining a non o visa on the back of hers. 

I need to do the visa extension by 19th Feb but there is a delay because I'm waiting for a document. 

The school has advised me to overstay and proceed when the document arrives. 

They seem to think that this will be okay and I just pay an overstay fine. 

I'm concerned that this will invalidate my current 3 month visa and I'll need to start the process all over again. 

Any thoughts from experience? 

Anyone here managed to get a visa extension when the current visa is on overstay? 

If the delay would only be a few days, the school is likely correct that immigration would extract the fine and then give you the extension. It is up to the officials you deal with, but most would not want to give the parent of a child in school a hard time. That said, I would be pretty reluctant about going on overstay if there was a viable alternative. Also, I would certainly not risk it if the overstay was going to be more than about a week.

Thanks for the reply BritTim.
Actually I had no need to overstay in the end as a trip to immigration to plead with them to not have to have the particular document was granted and they allowed me to proceed without it.  Thank you immigration!

 

The document in question is the legalisation of the birth certificate and the birth entry.  There is now a new process required and just having the originals is no longer accepted.  You must do the following (for UK documents)....

 

(1) send the original document to the UK legalisation dept in Milton Keynes UK (UK embassy in Bangkok does not legalise birth certs)

(2) After you have the legalised "apostille" (a piece of paper attached to original certificate) from Milton Keynes you send this to the Thai Embassy in London and they verify the signature on the apostille (this was the step I hadn't done)

(3) Once you have the London Thai Embassy stamp you then visit in person the Dept of Consular Services in Bangkok for a final stamp verifying the entire process with another stamp of approval

THEN your original birth certificate is now a valid and verified document to be used in Thailand!

 

You cannot just take the birth certificate with the apostille direct to Dept of Consular Affairs as they will reject it and tell you to send it to the Royal Thai Embassy in London (for UK docs).  I know because this is what I tried to do.

That is not a new process.

That has always been the process to have a UK document legalised to be accepted in Thailand.

I've lived here for 15 years and each yearly visa I have obtained I have always used originals of birth certs or marriage certs and never had them legalised. 

Last year I obtained the exact same visa on the back of my daughters visa and the original birth certificate was fine.  This year the same immigration themselves told me it was a new policy and they could no longer accept just an original but needed 3 extra verifications per certificate (1 on the UK side and 2 on the Thai side). 

 

For me at least this is a new thing :-)

It is relatively new that immigration is wanting marriage and birth certificates legalized.

Before the UK embassy stopped allowing a self certification of them by way of a statement it was an easy process. But having to do it in the UK certainly made it difficult.

Don't dispute that.
