A Permanent Residence Visa (PRV) is a document issued by the Government of Canada that allows a foreign national to live and work in Canada permanently. There are several categories under which an individual can apply for Permanent Residence, including:

1. Economic Class: This category is for individuals who have the skills, education and work experience to contribute to the Canadian economy. It includes programs such as Express Entry, Federal Skilled Worker Program, Federal Skilled Trades Program, and others.
2. Family Class: This category is for individuals who have close family members in Canada who are Canadian citizens or permanent residents and who can sponsor them for permanent residency.
3. Refugee Class: This category is for individuals who are fleeing persecution, torture or cruel and unusual treatment or punishment in their home country and who are seeking protection in Canada as a refugee.

To be eligible for Permanent Residence in Canada, an individual must meet the specific requirements of the category they are applying under and:

1. Be admissible to Canada under the Immigration and Refugee Protection Act (IRPA) and the Immigration and Refugee Protection Regulations.
2. Have enough funds to support themselves and their dependents after they arrive in Canada.
3. Not pose a security risk to Canada.
4. Not be inadmissible to Canada on health or security grounds.

The process to obtain Permanent Residence in Canada involves submitting a completed application, along with supporting documents, to a Canadian visa office. The processing time for a Permanent Residence application varies depending on the category, the visa office and the specific circumstances of the applicant.
