I am applying for an O-A Non Imm Visa from London Thai Embassy, I hope to return to Thailand in August 2019 after staying with family here in UK. If my application goes fairy quick and I obtain my Visa say in July 2019 will it only become active once I enter Thailand or will I loose maybe 1 month (this is my first O-A as only had tourist visa’s before) thank you🙏
TLDR : Answer Summary
The O-A Non Imm Visa becomes active once it is issued and attached in your passport. Therefore, if you receive it in July but enter Thailand in August, you'll effectively lose about a month of validity. However, many members emphasized that this loss is minor as the main focus should be on meeting the financial requirements for the visa extension after the first year.
