Hello,
I am here on a non immigrant O visa , valid to stay for 90 days...
Can I get tjis extended for 30 days more at a local immigration ?
Thanks
TLDR : Answer Summary
A Non-Immigrant O visa cannot be extended for an additional 30 days. You have options to apply for a one-year extension if you meet the requirements, or a 60-day extension if you have a Thai spouse or child.
