Green cards are permanent visas that allow legal citizenship in the United States.
When a foreigner possesses a green card, they are entitled to the same rights that all United States citizens enjoy.
These include the right to enter and leave the country at will and live legally in the United States.
The first eligibility requirement is whether or not you are immediately related to a United States citizen as follows:
Your spouse is a citizen.
At least one of your parents is a citizen.
You are the parent of a child who is a citizen and at least 21least twenty one years old.
You were adopted by a citizen before you were 16 years old.
Some green cards are issued on a first come first serve basis. Therefore, it is also best to speak with an immigration attorney immediately entering the country.
