I have a 5 year visa exemption sticker on my passport which says I am allowed to stay in vietnam for up to 180 days. I was wondering if I were to leave the country for maybe 1-2 days and say go to Thailand or Hong Kong and get a stamp saying a left the country , would this reset my 180 days and I could theoretically stay another 180 days in Vietnam?
I heard for tourist visa's you need to do something called a visa run and get a new tourist visa but I am wondering in my case, does simply exiting the country and then returning shortly reset the 180 days or would I need to get an extension or something?
