How soon before retirement extension expires can I renew?

…head into you local Thai Immigration Office. Take in a calendar and chat up someone who will go to bat for you. Explain your situtation. The Thai Immigration staff have all been incredibly polite and instructive in my dealings with them. Never act superior. Dress with long slacks and a shirt with a collar. It means much. Put it this way: “…how many us could do THEIR job, dealing with farang all day?”
