TLDR : Answer Summary

If you have a 90-day Non-O visa and are looking to extend it for 12 months, you can apply for the extension at any immigration office when you have 30 days or less remaining on your current visa. Some offices may allow you to apply up to 45 days before expiration.

You can apply at all immigration offices when you have 30 days or less left on your current stamp, a few allow you to apply when you have 45 days less left
