I came to Vietnam for several days, when I came to apply for a tourist visa for 25 days, spent 850 oceans, the exit gate gave 25 tips, I heard in the group that now Vietnam tourist visa from yesterday only 7 to 10 days, and in the past when the visa expired, you can also go out for a circle and immediately come back to get a tourist visa, now it takes more than 5 days to get out, so everyone must understand clearly in advance
