I will be going to Phuket immigration on Tuesday for a 60 day extension on my ME non o visa based on visiting Thai wife. I obtained a kor ror 2 last month when i went in for my extension however I did not apply for the extension after being told it would be effective from that day rather than from the 27th of September. My question is can I use the same kor sor 2 or do I have to get a new more recently dated one?
