Hi, need some advise. I have a Non-B Visa. In Feb, I went out via Tak Bai and came back in through the same way. I was stamped for 1 month and not 90 days as it should be. The stamp was not clear and I thought it was 90 days. Today, it was pointed out to me that it expires 26th Mar instead of 26th May (as I thought). I am in Chonburi. What can I do?
