CM is up to 45 days early.
You can try earlier and show flight ticket.
Your extension will only be issued up till date of expiry of pp.
12 months validity is fine.
If you withdrew the funds from one account and placed then in another that may cause an issue.
Sounds like you did that within 3 months of obtaining previous extension.
Most immigration offices do the extension from 30 days prior up till expiry of the 90 stamp.
Some offices allow up to 45 days early eg CW, CM etc.
Obviously do it early enough to attend to any added requests from immigration
Only one 60 day extension to visit wife per entry.
You can obtain non O from Savannakhet or you could do border bounce reenter visa exempt and obtain non O marriage in Thailand
Stop misleading posts.
Folk obtaining a non O from visa exempt or tourist visa entry have a non O and 90 day stamp accordingly.
They can then obtain subsequent ongoing 12 month extensions.
Interesting that you start a thread with basic question and then state the above
Some immigration offices do check and while I have never read report of rejection for not maintaining funds for under consideration period the advice you posted is poor.
It's boring?
As I posted there is current thread and many knowledgeable folk have recommended agent details.
This thread is Pattaya specific.
If you live in Bangkok you can contact @ThaiVisaCentre for advice who are involved with this forum. Many other agents that are mentioned often.
It's not difficult.
The rule is to maintain 800k+ for 3 months after application for extension and can then reduce to 400k and back up to 800k + two months prior to next application for extension.
As for change of account....
If you have the funds best option would be to wait till the 400k period and transfer 400k from existing account into new account and the remaining 400k 2 months prior to next application.
Please post something sensible.
Recommendations for agents are ask for in many threads.
In fact current thread on that.
I post agents names in many threads.
It's not secret information.
Couple of options.
Take border run to Cambodia which involves long gig in van
OR
Fly Udon Thani and bounce to Nong Khai bridge.
For me it would be return (cheap) flight to Saigon for a mini holiday.
Struggle to come up with a reason for it.
We all know that many folk now are obtaining non O retirement inside Thailand now for various reasons.
Address check for that reason anyone's guess
OP you mean border bounce for visa exempt entry.
That currently gives 45 day stamp.
Where are you located.
That determines best option.
Your OP is very vague
No.
Most folk had no idea what you were asking.
So you are doing border bounce to obtain visa exempt entry 45 day stamp to enable agent to obtain non O.
Answer : yes no problem.
