I am here in Thailand on a six month METV. Am I only allowed to get a thirty day extension to one of my sixty day stays, or can each sixty-day stay be extended?

First of all, thank you to the moderators for taking the time to host the platform. Question for the group on Thailand METVs: My wife and I are from the US, and are planning on staying in Italy for three months before visiting Thailand on an METV. Can we apply for the METV online while in Italy? We don’t want to apply for it while in the US, because our Italy portion of our trip would eat up three months of the six month visa.

I have a 6-month METV multientry visa, but I read that it is valid from the moment the visa is issued.

I don't know so because the other times the 180 days started the moment I entered Thailand,What do you think?
