Visa Extension Question Via Malasia Boarder

[davidst01]

My friend flew into Bangkok on 11th January and was stamped a visa until 10th Feb. She is currently on Koh Lanta island and wants to do a border crossing at Malasia on the 9th Feb.

Question is: How many days will they stamp her Greek passport at immigration when she does the border run? She has to fly out of Thailand back to Greece on the 25th Feb.

Many thanks

15 days - day of crossing is day one.
