this site is for people who want advice for possible immigration benefits, not for people who want to punish their ex's.
Answers given on this site are general advice only and do not establish an attorney-client relationship.
You should first consult with a libel lawyer to determine if you could be sued by your ex-wife for defamation and libel. If you have evidence and your lawyer clears it, I would suggest that you make an INFOPASS appointment with your local immigration office and without mentioning names, see if they're interested in following up on an investigation.
The solution to your problems lies exclusively in divorce court, not immigration law. Only ICE can determine whether or not to deport someone. You need to move on with your life.
J Charles Ferrari Eng & Nishimura 213.622.2255 The statement above is general in nature and does not constitute legal advice, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship. Answers on Avvo can only be general ones, as specific answers would require knowledge of all the facts. As such, they may or may not apply to the question.
