Hey my friend might be in trouble I hope you can help. He married an illegal for money but before signing documents for her to get her stutff he back

Your friend did a very stupid thing. Committing marriage fraud can result in steep fines and jail time. He should not make matters worse by pursuing immigration benefits on her behalf. He should immediately file for divorce. Most states do not require both spouses to agree to a divorce. However, of the spouses do not agree, the process will likely take longer.
