Hello. My father is a USA citizen and looking to return to Thailand to visit in August. He will be staying with me in my home during some of the stay and in hotels as he travels about Thailand. Is there still a special tourist visa with 3 months and two extensions totaling 9 months? Can he stay with me if he gets the special tourist visa? He wants to spend several months here this time if possible. What visa options does he have? Thanks in advance for your knowledge on this.
