What should my friend expect when entering Thailand through the Savannakhet/Mukdahan border with a Multiple Entry visa based on marriage?

The entry experience at the Savannakhet/Mukdahan border can vary significantly based on individual circumstances and the immigration officer on duty. Travelers with a Multiple Entry visa based on marriage may be asked to show around 20,000 baht in cash and may face a few questions regarding their residence and activities in Thailand. However, there are reports of travelers experiencing no inquiries or requests for documentation at all. It is advisable for the traveler to be prepared, but not overly concerned, as practices seem to differ widely.
