Correct application window for Visa extension (TM7)

[stateofmind]

I have done the 1 year visa extension (TM7) for my Non-B (investment) visa many times without problem. Most of the time I have done this 14 days before my current extension expires. But I have also done it as late as 12 days before expiry, and as early as 30 days before expiry.

 

Does anyone know the official requirements for when to submit the TM7? Is there a minimum and a maximum number of days before the current extension expires where this is permitted and/or preferred? Is there an official document on the Immigration website (Bangkok) where this is specified? I have tried to find it, but could not.

 

The reason why I ask is that this year my schedule is a bit tight, and I have to plan ahead.

30 days prior and 45 days for few offices and up till day of expiry.

Have they implemented the online application process of document submission for certain extensions?

 

It would be hugely useful to not have to go two or three times when new documents are required.
