This is the 2nd time I've used Thai Visa Centre to renew my retirement visa. Foreign retirees here know that our retirement visas have to be renewed annually and it used to be a huge pain and I didnt look forward to the hassle at Immigration . Now I complete the application, send it along with my Passport and 4 pictures and fee to Thai Visa Centre. I live in Chiange mai so I mail everything to Bangkok and my renewal is completed in approximately 1 week. Fast and uncomplicated. I rate them 5 stars!
