At Pattaya immigration office, previously, we were allowed to apply for the extension of non-immigrant O-A visa with in 3 months before the current visa expiry date.

Is it still allowed? I am out of Thailand now and planning to go to there just to get an extension

At immigration offices in other cities,it appears that we have to wait until one month before the visa expiration.

Thank you.

Three months is stretching it, even in Pattaya. Unless you have a documented good reason, at the option of the immigration officer, I'd go with one month.

Two months allowed at Jomtien with no excuse needed. Three months no longer allowed. It used to be Jomtien openly invited three months early, but not now. Most offices, one month is the standard. That is the current information based on reports here/local media. It can change at any time. If you have personal recent experience with a two month's early application, pro or con, please REPORT it here so we can keep this advice current.

I did it a little over 2 months to co-inside with my wife's spouse visa. The reason I used was we get confused when we have to renew our visa's on different dates, (she was 10 days overdue, I was 65 days early) No problem, no fine for her, very accommodating.

Thanks for the report. However, to be clear, the current information I am going on is that at Jomtien two months early is totally OK with no excuse asked for or required. I have no reason to believe that isn't true, unless someone reports otherwise.
