I quit my job and left the country for ten days. While I was gone, my former employer cancelled my work permit (as expected). I came back in Saturday night on a 60-day tourist visa and was pulled aside by immigration because I still have a multiple entry visa stamp in my passport that doesn't expire until December 2017. The immigration officer told me that I need to go to immigration and cancel the multiple entry visa. Can you tell me where exactly I need to go and how long I can wait before going?
