I’m Canadian. I have 6 months multi entry visa good from Nov 12 /18 to May 11/19. I just came back from a trip where I exited prior to the first 60 limit of stay. In the taxi back to Aonang from Krabi airport I’m concerned the lady at passport control has canceled the remaining visa? I have an admitted stamp till April 13/19 but the visa now has today’s stamp and two Pen marks across the visa. Is this something I need to be concerned about, as I am planning to stay till end of May.
