The Immigration and Nationality Act provides a yearly minimum of 140,000 employment-based immigrant visas which are divided into five preference categories. They may require a labor certification from the U.S. Department of Labor (DOL), and the filing of a petition with United States Citizenship and Immigration Services in the Department of Homeland Security (USCIS).

Family-Base Petition

Here are some efficient ways to be eligible for permanently immigrating to United States such as your close relatives are in USA who sponsor you (family based immigration), some professionals of a given occupation are in short supply in USA and your employer would like to sponsor you (employment based immigration), by applying in a lottery to win the permanent residence (not all citizens of all countries are eligible), political asylum, investment based and so on. This section describes family based immigration. Congress, by conferring permanent residence eligibility upon certain family-based groups, has properly emphasized the importance of family unification in American immigration law.

Green card immigration

A green card is a life-long visa ("pass") allowing a foreigner to live and work in the United States. The card itself is a government-issued plastic i.d. card that serves as proof of this permanent resident status in the United States. In size and format, it generally resembles a driver's license. The official title of the card is "Permanent Resident Card" and as it so happens, the card is not green. The nickname may have come from the symbolic nature of the color green in the United States: Green has come to mean "go," as it does on a traffic light.

US Citizenship

Citizenship is one of the most coveted gifts that the U.S. government can bestow, and the most important immigration benefit that USCIS can grant. Most people become U.S. citizens in one of two ways:
• By birth, either within the territory of the United States or to U.S. citizen parents,
• By Naturalization.
