CHANGE OF VISA TYPE inside Thailand
You need about 3 months total to go from a visa-exempt entry OR a single entry tourist visa, to first a 90 day Non-Imm-O retirement visa, and then to a one year Extension Of Stay Permit (based on retirement) because that's how long the process takes at most immigration offices.
This process is called “change of visa type”. For retirement purposes, click on number 9 on the website I linked for you. It will open a pdf. document in which the requirements are listed
You need to have a minimum of 15 workdays (!) left on your “admitted until” stamp in order to apply for the “change”.
If you have ever been on overstay and got listed in the Immigration computer, you CANNOT apply for the “change” any more
SO if you're not going to be here at least 3 months, you don't have the time to pull off getting a "retirement visa" by the “change of visa type” method – and from this one to the one year stay permit based on retirement. After you have been issued the “1-year Extension Of Stay Permit”, you are free to travel again
The inside country "retirement visa" (really the 90 day Non-O visa and a year extension) are sold as NO entry because you're already IN Thailand when you apply for them.
The process works like this:
Get here on a 60-days tourist visa or on a “visa-exempt entry”
*** open a bank account, transfer from abroad 840,000.- THB (800K minimum are required) In most offices, you will have to proof the money came from abroad.
At this stage, NO seasoning of the money is required (!)
*** go to the immigration office and apply for a 90 days Non-Imm-O retirement visa for 2000.- Baht
*** wait for the under consideration period to end, visit Immigration and pick up your passport with the visa (2-4 weeks depending on office)
*** Then wait until your 800.000.- THB funds are seasoned in the Thai bank account for 2 months. Visit your bank, get the “bank letter of guarantee” which certifies the 2 months period
*** - go to the immigration office, apply for a year extension based on retirement for 1900.- Baht (it will be issued the same day in most offices)
*** Once you get the year extension inked, you can buy a re-entry permit (single 1000.- Baht or multiple 3800.- Baht) and you will be ready to exit and re-enter Thailand and your stay permit will keep alive
And Bingo!
However you also might want to use the “convenient” method
You can apply by the online E-visa system in Spain, before you travel, for either
1. . . . . . a Single Entry Non Immigrant O visa (called retirement visa)
2. . . . . . or a Multiple Entry Non Immigrant O visa (called retirement visa)
3. . . . . . . or a Multiple Entry Non Immigrant O-A visa (called retirement visa)
4 . . . . . . . or a Multiple Entry Non Immigrant O-X visa (called 5-year retirement visa)
5 . . . . . . . or the LTR Visa (called retirement visa)
With one of these these, fly to Thailand, get 90 days or a one year admitted stay stamped, and later apply for the 1 year Extension of Stay Permit (also called retirement visa, but it is not a visa!) by fulfilling the required financial proofs
