Non o multi, visa expires June 25th 2020, permission to stay was till April 15th so now on covid Amnesty. Can I apply for a 60 day extension or a 1 year extension right up until 31st July? How long before the 31st should I apply?

You can apply for a 60 day extension to visit your wife or Thai child.

Being able to apply for a one year extension of stay is not clear yet since immigration may not consider the "automatic extension" a extension of your original non-o visa entry.

keep your 60 days for the 1st of august ...

OP, personally I would obtain your 60 x a few days prior to July 31.

So a 60 day extension may be possible under the Amnesty extension however we don't have a clear answer on whether one can apply for a one year extension under the Amnesty. I wonder if anyone has had some advice from immigration regarding this.
