Any lawyer that says K-1 is better than DCF is either ignorant about the visa process or trying to line his pockets. Tell your mother to contact King in GZ he is an immigration attorney who knows his stuff. These other shysters are trying to take you for a ride. DCF is the fastest possible way for you to bring your loved one home. Bar none, there is no faster way period. One she enters the US her status is automatically adjusted removing the head ache of AOS.
