I heard some one saying that "after they came to the United States illegally, their wives soon became pregnant, had more kids born in the states. Because the america-born kids are U.S. citizens, the illegal parents were able to get their green cards and later became citizens, too!" I would like to know if this is true and if so, I need to know how I can obtain green cards. (I am holding non-immigrant visa and have one child born in the U.S.) Thanks in advance for your information and advice!
