ORIGINAL POSTER

When you get you Non O or Non OA visa issued by the Embassy in the USA, what is the  "Enter Before" date shown on your visa ?

Just curious how long you have to enter initially after the visa is issued, and cant find anything on the embassy websites.

TLDR : Answer Summary

The "Enter Before" date on a Non-O visa allows entry into Thailand for 90 days from the issuance date. In contrast, a Non-OA visa permits entry for one year from the issuance date, but it requires proof of insurance, and the entry stamp may be limited based on the duration of that insurance.

Enter before that date, I'd have thought.

All Non-O are valid for entry to Thailand for 90 days from the day it is issued.

A Non-OA is valid for entry to Thailand for 1 year from the day it is issued, but entry requires proof of insurance and if less than 1-year, your entry stamp will only be until the end of your insurance.
