1991 Armed Forces Immigration Adjustment Act

The Armed Forces Immigration Adjustment Act 1991, also known as the Six and Six Program, was enacted on October 1, 1991. The Act amended the Immigration and Nationality Act of 1965, also known as the Hart-Celler Act.

The Armed Forces Immigration Adjustment Act allows aliens who have served in the United States Armed Forces for at least period of 12 years to be granted special immigrant status. Immigrants who have served for 6 years may also obtain special immigrant status if they re-enlist so their total service commitment is 12 years. Special immigration status may also be awarded to those who have a "recommendation by the executive department under which such alien served or is serving."

There are no numerical limits on how many special immigrant status visas can be issued. Special immigrant status visa holders are able to obtain permanent resident status, and the same applies to their spouses and children.

Some applicants for special immigrant status are also immediately eligible for naturalization as US citizens.

Provisions
There are a number of requirements that must be met before a person is able to apply for special immigrant status. 1.

Hart-Cellar Act
The Hart-Cellar Act (the Immigration and Nationality Act 1965) replaced the Immigration Act 1924 and eliminated the quota system put in place by the 1924 Act.

The Hart-Cellar Act created a preference system that recognized skills and family relationships.

"[A]ccording to De Genova, the 1965 legislation was celebrated as a liberal reform of the racist and exclusionary national-origins quota system that had been in place without substantial modification since 1882" 29 September 2014.

The new system set numerical restrictions on visas. However, it excluded immediate relatives of U.S. citizens or special immigrants born in independent nations, former citizens of the US, ministers, or employees of the U.S. government abroad.

Immigration Act 1990
The Immigration Act of 1990 increased the number of employment-based visas that could be obtained by immigrants from 54,000 to 140,000 per year and was heralded as "the most significant reform of the legal immigration system of the United States in nearly 40 years".

The objective of the 1990 Act was to improve "permanent immigration opportunities for most business persons, professionals and skilled workers" and its employment-based immigration changes became effective on October 1, 1991"

Armed Forces Immigrant Adjustment Act 1991
The treaty that allowed Filipinos to enlist in the United States Armed Forces is no longer in effect. However, "special immigrant status is still a possible routed to permanent residency for some people without other options".

Since eligibility under the Act was based on the status of the immigrant, service members were immediately eligible for naturalization based on service. However, foreign service members weren't well informed about the benefits of the Act.

Rogie Delmando, a Filipino service member who positively benefited from the Act, argued that "service members should be advised of this naturalization option immediately available to them if he or she has not filed for naturalization yet". Delmando also suggested other routes which might be better for foreign service members:
 * a.	some sailors from the Philippines who served during the Persian Gulf conflict can qualify for naturalization based upon service during a period of military hostilities;
 * b.	applying for special immigrant status under the Armed Forces Immigration Adjustment Act would normally be unnecessary because a more direct route to citizenship exists through service during the Persian Gulf conflict or another designated period of hostilities.
