@John ********
I paid in Thai baht,although I heard recommendation that us dollar is the preferred currency,was told by the "police" that 2000 was required,I must admit that I didn't do any homework until I had left and am still unsure what the correct price should be,a 30day visa was issued and that was that,som nam na on me if the price was too much ,not sure what you mean about where from,the border called Chong chom in Thailand and once across the border the "village"is called O'Samach..
