I had arrived in Bangkok July 22, 2025 contacted Thai Visa Center about Visa extension. I was concerned about trusting them with my passport However, I figured They have been advertising on LINE for years and if they were not legitimate I am sure they would not be in business by now. I was instructed to obtain 6 photos and when I was ready a courier came by motorcycle. I gave him my docs paid the fee by transfer and 9 days later a man returned by motorcycle and presented me with my extension. The experience was quick, easy and the definition of excellent customer service.
