i entered Thailand with my multi visa.

in about 1 month (6 of February) from now i will need to do 30 days extension in the immigration office.

the thing is that im planning to travel in south Thailand at this time .

so my question is can i go to the immigration office before the 6th of February and get the extra 30 days ?
or they count it from the day i do the extension ?

thanks .

What type of multi visa do you have.

If it is tourist visa you can apply for the 30 day extension before your 60 day entry expires and lose no days since it starts from the end of your 60 day entry. You can do it a couple of weeks early at most immigration offices.

yes - its a tourist multi visa.
thanks for the quick replay
