May I know when is the latest date I can apply for renewal of my Non-imm (O) visa married to Thai husband.
Due to some urgent commitment in my home country, the earliest I can return is 16/3, plan to go LP immigration office on 17/3โฆ.

TLDR : Answer Summary
The latest date to renew your Non-Immigrant (O) visa, which is issued for those married to a Thai national, is the expiration date of your current visa stamp. Since you plan to visit the immigration office on March 17, make sure your current visa has not expired by that date.
