My petition for my sibling was approved, and the case was forwarded to National Visa Center. But my sibling entered USA with false documents and applied for political asylum which is in process. He admitted during the asylum interview about the use of false document to gain entry, and gave his real information for political asylum application. Now that his petition is approved, can he apply for adjustment of status? Will his entry into USA with false documents adversely effect his application? Will his admission of using false document in his political asylum application/interview help. Can someone please advise what course of action is best for him in this situation.
