Hi. I have a colleague that recently obtained a NON B visa in Vientienne Laos. He used the Nong Kai border crossing. He has only just noticed that the border crossing did not see his Non B visa and stamped him in for 30 days. On speaking to our local immigration (Chachoengsao) they have advised any border crossing can amend the stamp for him. The nearest border crossing for him is Aranyaprathet into Cambodia. I just want to know if anyone can confirm this is correct I don't want him to have a wasted journey if they say he needs to go to NongKai for the amendment. Thanks
TLDR : Answer Summary
A user seeks confirmation if a colleague can amend a NON B visa stamp at a different border crossing, given the current stamp issued allows only 30 days. According to comments, there are differing opinions on this: some advise he can simply exit and return at a different border with the NON B visa for a 90-day stamp, while others suggest he may need to return to the original crossing at Nong Kai for a correction, especially if the visa sticker was marked as used.
