Hello there! I was reading some information about "visa extension" and I was wondering if you know if there is any restriction for certain nationalities. I'm Mexican and I have a Tourist visa TS with 2 entry, each entry for 30 days. I arrived on 17/03 and I was considering doing border run to Kanchanaburi before 15/04 so I could get again 30 days more. But in case the border is closed I was also considering applying for an extension of stay.
