I'm a USC and my wife is a Chinese national that just got her green card this past November.She had just travel back to China two weeks ago(January 2013) to try and bring her son (my stepson) over. Her son is 13 yrs. old. I file a I-130 petition on his behalf back in December of 2012. USCIS send me a notification letter acknowledging receipt of my petition on the 10th of December and are currently reviewing his application. My wife is there waiting with my stepson in China for "news" from the American consulate in Guangzhou. We have no idea how long the wait is gonna be and weather I should file a K-4 visa for him so that he and my wife can come back here immediately. Please advise!
