There has always been an immigration quota for spouses and unmarried children of green card holders, to immigrate to the USA. That quota typically took 3-7 years before being able to get a green card, thereby keeping many families separated from one another.Just recently,in the late-summer of 2010, that green card quota has surged ahead so that instead of waiting 3-7 years, these individuals only need to wait about 5 months. In past years, the spouse of a green card holder would not even have a case filed, rather they would wait five years until the green card holding spouse became a USA citizen, before filing a case. That strategy no longer makes sense with a quota that takes only 5 months. As a result, our office has been filing many of these "2a preference cases," in order to allow families to legally immigrate and be together again.The green card sponsor, such as the parent sponsoring unmarried children, does not even need to be in the USA to file the case. The entire visa petition process is all done by mail.
