Permanent residency refers to a persons visa status: the person is allowed to reside indefinitely within a country despite not having citizenship. A person with such status is known as a permanent resident. Citizenship is the political rights of an individual within a society. Green cards were formerly issued by the Immigration and Naturalization Service (INS). That agency has been absorbed into and replaced by the Bureau of Citizenship and Immigration Services (BCIS), part of the Department of Homeland Security (DHS). Shortly after re-organization BCIS was re-named to U.S. Citizenship and Immigration Services (USCIS).
Thus, you can have a citizenship from one country and be a national of another country. For example,a Cuban-American might be considered a national of Cuba due to his being born there, but he could also become an American citizen through naturalization. Nationality derives from either place of birth (i.e. jus soli), parentage (i.e. jus sanguinis), or ethnicity and religion (as in Israel). Citizenship derives from a legal relationship with a state. Citizenship can be lost, as in denaturalization, and gained, as in naturalization.
Not every country has a facility for someone to be a permanent resident citation needed] All European Union countries have a facility for someone to become a permanent resident though, as EU legislation allows for an EU national that moves to another EU country to attain permanent resident status after residing there for five years. Permanent residents may be required to fulfill specific residence obligations to retain their status. In some cases, permanent residency may be conditional on a certain type of employment or maintenance of a business.Some countries have compulsory military service for Permanent Residents and Citizens. For example, Singapore requires all males who are citizens and permanent residents to complete a compulsory 2 years of service in the army known as National Service (NS) upon attaining 18 years of age.
However, most first generation permanent residents are exempted, and only their sons are held liable for NS. People who are granted permanent residency in a country are usually issued some sort of documentary evidence as legal proof of this status. In the past, many countries would merely stamp the persons passport indicating that the holder was admitted as a permanent resident or that he/she was exempt from immigration control and permitted to work without restriction. Other countries would issue a photo ID card (known in the United States as a green card or would issue a visa sticker in the person's passport or present them with letter to indicate their permanent resident status. There is a growing number of fraudulent green card lottery scams, in which agents take money from applicants by submitting application forms for them, usually for a fee between US dollar 50 to US dollar250. Some claim that they can increase the chance of winning the lottery.
This is not true in fact, they may delay or not submit the application. Likewise, some claim that they provide free airline tickets to winners or other benefits, such as submissions in future years and even cash funds. There is no way to guarantee their claims, and there are ample reasons for them not to fulfill their promises. Due to the Heart Act foreign workers who have owned a green card in 8 of the last 15 years and choose to relinquish it will be subject to taxation on unrealized gains above dollar 600,000. However this will only apply to those people who earn greater than dollar 139,000 a year or have a worth of more than dollar 2 million. If the green card is not reliquished then the holder is subject to double taxation when working outside of the U.S. whether or not it is within their home nation.
