If you arrive on a Tourist Stamp for 30 days, (any country) You can bring all of your documents and income proof, photos, etc. to Immigration and pay 2000 Baht for an "O" Visa and then pay 1900 Baht for a "O-A (retirement) extension." This will be good for 15 months. Add to this the Re-entry permit charge if needed and you are set.
I was planning to get a Re-entry permit (100 Baht single entry) so I would not loose my "O" Visa extension. I was stamped in "valid until November 1, 2014." I had a trip end of March to return in May. Was planning to do the O-A Retirement extension at that time. I pay an additional 1000 baht extra, (1000 Baht for Re-entry vs. 2000 Baht for a new "O" Visa.) But I gain 3 extra months plus the time I am gone (April).
So in my scenario, this is the best way to move forward I think.

?Question?
1) After the 15 month "O-A" extension, do you renew every 12 months there after, year after year?
2) What is the earliest that you can renew your "O-A" extension? Normal is last 30 days, but how much earlier will they allow, if you will not be here during your renewal date or the 30 days prior?
