Individuals with lawful permanent residence (green card) status in the U.S. are permitted to live and work here on a permanent basis. Becoming a lawful permanent resident of the U.S. does not jeopardize home country citizenship status.
In general, lawful permanent residents have the same rights and privileges of U.S. citizens, but there are several important exceptions, including the right to vote.
Departure from the U.S. for lengthy periods of time can jeopardize permanent residence status, as can the commission of certain crimes.
Individuals holding lawful permanent residence status may become eligible for U.S. citizenship.
A limited number of "green cards" are available each fiscal year. These green cards are issued using a quota-based system. When the numbers are exhausted, backlogs develop in the availability of green cards. The U.S. Department of State publishes a monthly Visa Bulletin containing information on green card availability and backlogs.
