one of many possible visas. Review options on Official Thai visa website. Passport, enough understanding of regions of Thailand to choose where will suit you, prior time in Thailand to help you truly understand cultural, financial, language, transportation, issues you will experience. This can be a wonderful place to be. I moved here at 72 after more than 20 visits including one six month stay. I traveled to multiple parts of the country before choosing Isaan as my base. I am still weak with the language and depend a l;ot on my Thai wife whose grasp of English eclipses my grasp of Thai, and Google Translate is my constant companion. I cannot tell from what you have stated how much due diligence you have done. Please, if you have not done so, do much due diligence research. Forms such as this can give you ideas about what to research. They will give you some answers, but even research those answers, including mine. I am happy here, and it is not all sunshine, smiles and roses. It is a major life transition. It means learning to accept Thai culture and not expecting Thai people to meet the cultural expectations that ar the norm in the US. It means having a willingness to be learning every day, major amounts of patience, especially with the concept of Thai time. It means learning that while most Thais are wonderful and kind, they live and do things at their own pace. On time can be one or two or three or more hours later, which is OK in Thai culture. It can even mean canceling an appointment and not telling you unless you think to ask and confirm, and even then the confirmation can mean a time delay. I could write a book about all the myriad little things that take gracious acceptance as they differ so much from US expectations. With all that said, I love it here. I am building a small house in the countryside. I have a good car and motorbike. I have a Thai bank account, a helpful local pharmacy and a Dr. and Dentist I trust in nearby cities. I have a Thai family in addition to the US family I moved from. Nothing is all good. Andi I get up every day and review everything and there is so much good that I have no regrets for having moved here. You can D< me with questions if you want. You will get the most useful consultation from me if you have already done some dur diligence research so that your questions come from a place of some knowledge base. I wish you blessings.
