PR visa stands for Permanent Residency visa. It is a type of visa that allows an individual to live and work in a country on a permanent basis. A person who holds a Permanent Residency visa is also known as a Permanent Resident or PR.

To obtain a Permanent Residency visa, the candidate must show a significant connection to the country, such as through close family ties or financial investment. Depending on the country, different requirements and application procedures apply.

Generally, the candidate may need to pass a background investigation, satisfy specific financial or income standards, and pass a language competence exam.

Once an individual has obtained a Permanent Residency visa, they will typically have many of the same rights and privileges as a citizen of the country but may not have the right to vote or hold certain government positions. The Permanent Residency visa has additional restrictions or requirements that must be met in some countries. 

It’s important to keep in mind that a permanent residency visa is different from a temporary visa, such as a student, work, or tourist visa. They often have a short expiration date and cannot be renewed.

A permanent residency visa is typically valid for an unlimited period of time or as long as it takes the country to fulfill its requirements. It can be renewed, and, in some cases, it can even lead to citizenship.
