It is also not a requirement via the Thai Embassy in WA DC. I would just write a letter saying I am retired, get it notarized along with the other documentation and not loose sleep over it.
Interesting. I have never seen this requirement from the LA Thai Consulate. Here is what the Chicago Thai Consulate web site states - VII. Retirement in Thailand (O-A visa), the applicant must be at least 50 years old and must submit documents as follows :
documentation showing proof of retirement.
bank statement or monthly/year income.
a copy of the applicant’s criminal record from the local police department.
