My ex-"husband" used me for a green card and we divorced a year after the marriage and separated 7 months after marrying. He got his conditional green card based on the marriage. I reported him for fraud at U.S.C.I.S. and spoke directly to an immigration officer and gave her the evidence I had, affidavits, record of him texting another woman, etc..She took on the case directly and put it in his file and said that he will be questioned when he applies for his 10 years green card. But she told me that he has not applied yet for it, and I don't know if he will because he has like 2 weeks left until his conditional expires. I don't have hard core evidence that he used me, but I do have circumstantial, like that he got engaged to a girl back home even before our divorce was final.
