This is the third time for Thai Visa Center (TVC) helping me get my non-immigration O visa renewed. Grace and her staff responded very quickly and professionally to handle my questions, concerns and visa documents. I extremely like its messenger service to handle my original passport. On Mar 15 their messenger picked my passport, and 6 days later on Mar 20 I got my passport with newly extended visa. TVC is a great company to work with. It can be trusted to get your visa done.
