Former citizens or persons of origin Some countries grant residency and other specific rights to former citizens or persons of origin in the country: India does not permit dual citizenship, but former Indian citizens, and persons of Indian origin, are eligible to apply for an
Overseas Citizen of India (OCI) card that allows them to live and work freely in India, apart from running for certain political office posts and occupying constitutional posts. They also cannot vote or buy agricultural land. Spouses who have no other connection to India other than being married to someone with or eligible for OCI can also apply for OCI if they have been married for at least two years. If the marriage be dissolved, OCI status would be automatically lost for the spouse with no connection to India. In 2016, India allowed Permanent Resident Status to foreigners with some conditions. Turkey allows dual citizenship, and former Turkish citizens by birth who have given up their Turkish citizenship with permission (for example, because they have naturalized in a country that usually does not permit dual citizenship) and their descendants subject to certain conditions, can apply for the
Blue Card (), which gives most of the citizens' rights back, e.g. the right to live and work in Turkey, the right to possess land or the right to inherit, but not the right to vote or the right to be employed as a public servant.
Treaties Some countries have made treaties regulating travel and access to the job markets (non-government/non-military-related work) • A citizen of an EU country can live and work indefinitely in other EU countries and in Iceland, Liechtenstein, Norway, and Switzerland (and citizens of these countries can live and work in EU countries). Permanent residence is acquired automatically after five years of residence. • The
Trans-Tasman Travel Arrangement between Australia and New Zealand allows citizens of the two countries to live and work indefinitely in the other country, but the status is distinct from permanent residence in the country and expires each time a holder leaves the country. Despite this, the time a New Zealander spends in Australia on a Special Category Visa may count as permanent residence the purpose of acquiring citizenship. • A citizen of a
Gulf Cooperation Council (GCC) member state (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) can live and work in other member states. However, for voting, being voted and working for the public sector or the national security in a country, citizenship of the country concerned is almost always required.
Investments A "
golden visa" is a permanent residency visa issued to individuals who invest, often through the purchase of property, a certain sum of money into the issuing country. Dating back to the 1980s, golden visas became much more popular and available in the 21st century. Golden visas require investments of anywhere from $100,000 in
Dominica up to £2,000,000 in the UK. The most common method for obtaining a golden visa is through the purchase of real estate with a minimum value. Some countries such as Cyprus and Malta also offer
golden passports to individuals if they invest a certain sum. The issuing of so-called "golden visas" has sparked controversy in several countries. Since the 1990s, some countries have begun to offer golden passports - which give citizenship as well as residency rights - to foreign nationals who invest (often through the purchase of real estate properties) a certain sum into the issuing country's economy. The issuing of EU passports by
Cyprus and
Malta has sparked controversy but is expected to produce billions of euros in revenue for the issuing countries. == Limitations of permanent residents ==
