What are the options for a longer stay in Thailand on an Italian passport without frequent visa runs?

Or do 30 day extensions at immigration to limit border runs. Might be easier depending on location.

@Dominic ****

yes every 60 days or every 90 days if you do a 30 day extension at immigration for ฿1,900....

@Ke***

would Sydney be nearest to you? This is the page for the Sydney consulate:

I am in Australia, I cant find any mention of that visa on Camderra Thain Embassy web site, I am interested in it myself.

You can apply for it again when it runs out. It's up to the individual consulate policy as to whether there comes a point they may refuse you for apply for too many, but many Western consulates seem not too picky about it.

If you were applying for one of these per year, and then going doing something else for the other six months, I think you could keep rotating on these forever, I know people who winter here every winter, stay 6 months or even a little more but do also go home for the summer and then get another METV before they come back and no problem doing that.

On the other hand, if you were going to try to live in Thailand on this continually, even if the consulate in Rome kept giving them to you, immigration particularly if you enter through a Bangkok airport would probably stop you at some indeterminate point. It's not for living here on continually. Every winter rinse and repeat could be OK though.
