Adjustment of status  is a process that permits certain people in the 
    United States to apply for lawful permanent resident ("green card") status 
    without having to go abroad. Not everyone qualifies for this procedure. 
    Those that do must apply with an office of the U.S. Immigration and 
    Naturalization Service ("USCIS") and all further processing will be done by 
    that agency.
    
    Advantages of Adjustment of Status
    
    Adjustment of status has two principal advantages:
    First, 
    it does not require that the applicant go abroad at any time prior to the 
    grant of lawful permanent resident status. This is vitally important to 
    those applicants who have accumulated more than 180 days in "unlawful 
    status" and would otherwise be subject to a three year exclusion upon their 
    departure from the United States. For such people, who are also eligible to 
    file for adjustment of status under the "grandfathering" provision of 
    Section 245(i) of the Immigration and Nationality Act, this is their only 
    real option. Were they to go abroad to apply for an immigrant visa, they 
    would be subject to the three year exclusion.
    The 
    second principal advantage is that an applicant who 
    requires a waiver of exclusion may remain in the United States while the 
    waiver is being processed. As only a tiny handful of applicants ever require 
    waivers, this is not of great significance to the average applicant. It is, 
    nonetheless, a significant advantage to those who do require waivers.
    
    Disadvantages of Adjustment of Status
    
    There 
    are several significant disadvantages to applying for AOS. 
    First, there is the delay involved in AOS processing. A person wishing to 
    apply for AOS today should be prepared to wait a minimum of five years for 
    an adjudication. During this time, employer sponsored applicants may not 
    leave their employers or even accept promotions.
    A 
    second disadvantage is the discretionary decision making authority of 
    USCIS officers. Where one officer may see nothing, another may see 
    preconceived intent or presumed fraud. In such case, the officer has the 
    discretionary authority to deny the adjustment of status application. This 
    is very similar to the authority of consular officers deciding nonimmigrant 
    visas (consular officers do not have similar authority when they decide 
    immigrant visas).
    A 
    third and final  disadvantage to AOS processing involves the 
    legal grounds for denying an application. Anything that would result in a 
    denial of an application for an immigrant visa at a consular post abroad 
    automatically requires a denial of an application for AOS 
    in the United States. In addition, there are several independent grounds 
    that require the denial of an AOS application, but not the denial of a 
    consular immigrant visa application. For this reason, on a per capita basis, 
    denials of AOS applications were about fifteen times 
    greater than denials of consular immigrant visas during fiscal year 1998. 
    For the first three quarters of fiscal year 1999, the number of per capita 
    denials has grown to twenty five times greater.
    One of 
    the greatest and most persistent myths about AOS processing 
    is the belief that if an AOS application is denied, the applicant can easily 
    return to non-immigrant status and go on as if the AOS application had never 
    been made. This is simply not true. If a person is denied AOS because of 
    serious personal misconduct, they may well be taken into custody immediately 
    and held until they can be physically removed. Even when this is not the 
    case, and a denied applicant is not taken into custody, he or she must leave 
    the United States within a very short period of time and will find it 
    extremely difficult to ever return. It is the extremely rare case in which a 
    denied AOS applicant is allowed to remain in the U.S. or easily re-enter.
    
    Dependants
    
    The 
    person who qualifies as an immigrant is know as the principal applicant. All 
    qualifying dependants of the principal applicant are entitled to apply for 
    AOS as well. A qualifying dependant is defined as the 
    spouse or unmarried child (under the age of 21) of the principal applicant.
