On September 07, 2006 my mother filed an I-130 petition (Married Sons and Daughters of U.S. Citizens) for me, my wife and childrens. Then on July 12, 2010 the USCIS mailed my mother a notice that they have approved the petition. Then on October 21, 2010 The National Visa Center sent my mother a letter with the case number SDO2010752101. They said there's not visa available by this time and that they'll let us know when there's one available. Now we're just waiting and waiting.
