Have just used Thai Visa Centre for my 12 months extension, I also needed a multitude re-entry permit and all necessary stamps to be transferred to my new passport. As soon as i contacted them they responded with a courteous and professional manner and therefore, I felt comfortable and confident in proceeding with their service. The whole process took only one week to complete during which time I was kept updated throughout. Everything I sent was returned safely and without error and so I cannot honestly find anything negative to say. I will definitely continue to use their services in the future and highly appreciate and recommend them based on my experience. Thank you Thai Visa Centre 🙏
