How far ahead can I get an extension on a visa free entry? Have just arrived from Singapore to Krabi 5 days ago on a 30-day exempt stamp (Canadian passport). I want to go relax on Lanta, can I just go to Thai immigration in Krabi town to extend my "visa" now before I go to Lanta even though it's not close to the end of the 30 days? I'd like to relax on Lanta without worries, and it's a giant pain to hire a car to drive from Lanta to Thai immigration in Krabi town (about 3 hours) in 3 weeks to extend it if I decide to stay longer on Lanta. Would the immigration office let me do the extension before I go to Lanta?
Thank you for any info!
