Agreed. If from the UK you do the following before leaving for Thailand with your Non-O (find out the process relating to your "home" country) in order to get your in country extension -

1. IN THE UK: Marriage certificate legalised by the FCDO in Milton Keynes

2. IN THE UK: Marriage Certificate AND the Apostille from the FCDO Translated

3. IN THE UK: Marriage Certificate AND the Apostille from the FCDO AND their translations verified by the Thai Embassy in London

4. IN THAILAND: All the above (i.e. all 4 documents & their translations, making 8 in total) Legalised by MFA in Bangkok

then register your marriage at your local Amphur

@Derek ****************

yes it will

@James *****

multiple Non-Os per year is not a problem

@Ian *****

better to arrive on a Non-O ;)

@Julian ******

The OP is getting a retirement visa

You should get a certificate of residence and your Thai sim registered to your passport and try more branches and you'll succeed

@Julian ******

There is no Tourist Non-O, the Non-O is your retirement visa

@Julian ******

The Non-O is your retirement visa then in country you apply for an extension ;)

@Art ******

The law has not changed but now it is being enforced for those abusing the system

@Art ******

Why will he be denied? Don't just throw that out without some justification.
