when they processed my cancellation they maintained our original expiration date of 11/Nov we left early because I do not like to leave these things to the last day just in case there are any issues. For example if they denied allowing us to exit Thailand for any reason we would have have quite a few days left to rectify the situation.
thank you so much. This will be my first time doing a land crossing. Just to confirm I will be able to extend the visa exempt entry in Chiang Mai for an additional 30 days correct?
