Can I extend my 30-day visa exemption in Thailand and what are my options?

Yep, you can't use the eVisa website outside your country (you have to show a flight from your country here to get it approved)

Yep you certainly can (y) Come back in on a free 30 day visa exempt and then take the one 30 day extension you're allowed on it for 1900baht at the immigration office that serves the area where you stay in thailand.

You are allowed TWO free 30 day entry by LAND in a calendar year, no need to fly out and back to get a new 30 day entry stamp

𝗜 𝗯𝗲𝗹𝗶𝗲𝘃𝗲 𝗜 𝗰𝗮𝗻 𝘂𝘀𝗲 𝘁𝗵𝗲 𝘃𝗶𝘀𝗮 𝗲𝘅𝗲𝗺𝗽𝘁𝗶𝗼𝗻 𝘂𝗽 𝘁𝗼 𝟯 𝘁𝗶𝗺𝗲𝘀 𝗶𝗳 𝗜 𝗮𝗿𝗿𝗶𝘃𝗲 𝗯𝘆 𝗮𝗶𝗿 - 𝗶𝘀 𝘁𝗵𝗮𝘁 𝗰𝗼𝗿𝗿𝗲𝗰𝘁? Nope, that is not correct, and officially there's no limit to the number of 30 day visa exempt entries you can get by air, BUT what you're not gonna be able to do is live here on back-2-back free entries without getting pulled aside and asked WTH you're doing trying to live here on free stamps OR worse getting denied entry when they think you've had enough free entry.

Your plan is fine, go do your vacation in Lao for a week, come back on a 30 day free entry stamp, take the 30 day extension <- that's the two months you're wanting
