# Retirement visa: non-O vs. non-OA
I'm not sure if I'm missing something, but why is almost everybody in this group speaking about getting the non-O retirement visa, valid for 3 months only and then issuing a non-OA retirement visa for 1 year - already in Thailand?
According to the eVisa site ([members only]), the only additional documents for non-OA are:
1. A medical certificate
2. Foreign Insurance Certificate
3. Health Insurance
4. Certificate of criminal record clearance
Is it so much more difficult to get those documents that it justifies additional bureaucracy in Thailand? In my mind, preparing everything in the origin country and getting a 1-year visa before entering Thailand is much more convenient - but maybe I'm wrong?
