Regarding Vientiane giving a red stamp after 3 or 4 Visas...
Let's say the magic number is 4. Is that 4 in a row from Vientiane? Or 4 from Vientiane total. In other words, what if you alternate between Vientiane and Savanakhet? Will Vientiane red stamp you after you have:
1) 4 total visas from either consulate
2) 4 visa from each consulate, so a total of 8 visas
3) Or will they allow you to get more than 4 from Vientiane because you alternated and didn't get any from Vientiane back-to-back
And how about Savannakhet? Will they issue more than 4?
