My ex wife talk to immigration that our marriage was arrange after we have withdraw the case and am married to another person

If you were involved in a bona fide marriage, you have nothing to worry about. You will need to gather evidence that you were actually married to your former spouse. If your spouse has declared the truth to USCIS, then you have a problem on your hands.

Immigration often get angry ex wives and husbands saying things. He said, she said isn't a good basis for any action. There would probably have to be real evidence as well.

If there is evidence the marriage was entered into in good faith and you had a bona fide relationship you may be able to overcome your wife's statement with the evidence. Speak with an immigration attorney.
