Can I get 30 day extension on 60 day tourist visa anytime?

[AlphaCanadian]

Last week I got a 60 day tourist visa issued in Malaysia. I am certain that I will need the 30 day extension when my 60 days is up (for a total of 90 days).

 

No reason to wait on having this done. Can I go to the immigration office in Bangkok (where I am staying) and have the 30 day extension stamp at any time?

 

I wonder if they will tell me at immigration that it is too soon to have this done.

 

Thanks in advance.

I don't have personal experience, but from others posts it reads that is usually not accepted longer than a week before expiry of the current stay.

Normally the extension cannot be done until the last 2 weeks of the 60 day entry.
