How long can I stay in Laos?

20 1 1 have been to Laos. A tourist visa can stay for 30 days at a time and can be renewed twice, that is, it can stay for 90 days at a time. However, we are in Vientiane, just across the river from Thailand. In 90 days, we will go through the exit formalities from Friendship Bridge in Vientiane to Langkai Port in Thailand on the other side, then go through the entry formalities again and re-enter Laos. We can stay for another 90 days. There are local Laotians who specialize in this kind of business and can speak Chinese. You just have to follow, and he will do all the formalities for you. I don't know how long the stay of business visa and work visa is.
