Thanks to Tod and the other "Moderators" on this site I did my 1 Year Marriage Ext at Chaeng Wattana yesterday (02.02.2022) in record time. We even got a thank you for using the online appointment system. My wife said the IO was impressed with the Presentation and Preparation of my documents. Thanks again for the Info you guys provide.
A couple of points raised on this site recently;
No ATK Test, just filled out the Form.
6 Months Bank Statement , Bank Letter and Up Dated Bank Book 300 Baht. (Took Just 15 Mins).
Ext is now "Under Consideration" until 2nd March and I'm looking to book an online Appointment, but cant see "Under Consideration" listed on the system. Is it not possible?
TLDR : Answer Summary

They highlighted that no ATK test was needed, only a form and required documentation including a 6-month bank statement, bank letter, and updated bank book. After the extension was submitted, it was marked 'Under Consideration' until March 2nd. Users in the comments discussed their experiences with follow-up visits for final stamp collection, noting that usually no appointment is necessary and wait times can be short.
