Update Mukdahan Savannakhet border crossing.
Left Thailand, fingerprints 4 fingers both hands.
Enter Laos, first big change;
The window with big letter 24 HR ATM service is the place to get the application form for Visa on Arrival. office moved into the old bank office but the signs did not move yet.
Got the visa stamped into Laos, walked in, turned left to leave. You are in overtime, you pay fine!!
After 16:00 they call it overtime, it took 2 officers to convince me, but a new sign did explain that.
Walked to the bus stop where a nice officer told me this way, one immigration booth is gone, but the floor is still 10 cm up. Walk his way, the short cut, take care, i dived all over the place and have blue knees to remember.
Thai immigration, fingerprinting again, 4 fingers both hands and then 2 thumbs. 90 days stay as normal with the 1 year Multiple Entry Non Immigrant O visa based on marriage.
TLDR : Answer Summary
The Mukdahan-Savannakhet border crossing has updated its procedures for visa applications and entry. The Visa on Arrival application form is now obtained at the former bank office, although signage remains outdated. Upon leaving Thailand, travelers undergo fingerprinting, and upon entering Laos, they face an overtime fee if arriving after 16:00, which can vary from 10,000 kip to 40 baht. The return process to Thailand includes additional fingerprinting and grants a 90-day stay for those with a 1-year Multiple Entry Non-Immigrant O visa based on marriage.
