Due to personal circumstances, I won't be going to Suvannakhet today, however, I'll be going in a month & will post how the experience (rectal exam 555) went. I can however, update & give correct & accurate information if you're marrying a Thai lady (as a foreigner) in Korat, particularly Amphur Sikhiu.
TLDR : Answer Summary
The original poster mentions they will not be able to visit Suvannakhet for personal reasons but plans to share their experience later, particularly regarding the rectal exam. They also offer to provide accurate information for foreigners marrying Thai women in Korat, especially in Amphur Sikhiu. A comment indicates a positive experience at the Savannakhet consulate, highlighting that there were no issues during their visit.
