How far in advance can I apply for a visa extension in Nakhon Sawan before my 60-day TR visa expires?

Thx

Lisa / Martin/ Kev you have been active in this an other groups for a while now so surely you have read too that the COVID-19 extension u only get once u have used up your normal extensions. I was just unsure how early I could do it in Nakhon Sawan since every office seems to have its own rules.

So first the 60+30 and in my case then either +60 Thai family or change to Non O Due to marriage for a further 90 and then 1 year renewal. which is the better option for me since I can have a WP too

But that will probably be in the next year or two... have to earn a few million more first lol
