One of the key stages in the immigration process to Thailand is obtaining a permanent residency visa or permanent residency. While the term "Permanent Residency" (PR) is more familiar to Eastern Europeans, Thais often use this term to refer to the same type of authorization.
An essential requirement to get a PR is continuous residence in the country up to 3 years on a non-immigrant visa (NIV). There are different types of NIV depending on the purpose of your stay in the country. It's worth noting that not every non-immigrant visa is suitable for a subsequent application. As an example, the popular student visa, which is obtained when enrolling in a local university or language school, as well as the retirement visa to wealthy citizens over the age of 50, do not grant the right to apply permanent residency.
