I am here on a 60 day visa free entry and would like to have the option to stay another 30 or 60 days without going to Immigration. I would like to visit Lao for a few days as soon as my current entry is about to expire. When I re-enter by land, will I be give 30 days or 60 days? I am a US citizen currently in Chiang Mai. This is my first visit in years if that helps.
