I’m planning to cross the border to Laos using the Chong Mek crossing going to Pakse.  Does anyone know if I can get a re-entry permit at that crossing?  If not where is the nearest place to apply for one.  Thanks in advance. 

As far as I know they do not have a re-entry permit desk at th Chong Mek crossing.

There are two immigration offices here in Ubon Ratchaithani. 

There is one in the city at Rajabhat University. Map: https://goo.gl/maps/eWcUF8ZhEpq

There is also one in Sirindhorn on Hwy 217 on the way to Chong Mek. Map: https://goo.gl/maps/wedRvRaneQz

 

Thanks for that.
