Hi, i am enquiring obo my son. He will be doing visa run to Cambodia on 7th Sep. He needs to cancel his current ED visa before he does the visa run. He will be going to immigration on Monday, 5th. There will be a 2 day delay before he does visa run. How do you get around this? Will immigration cancel visa effective Monday 5th and he must leave country or do they at least give you a few days to leave and if so is there a cost involved?
