Thank you for inviting me to start a new thread.
What is the reason you were asking about the I-864?
I ask because I am in a similar situation. His visa was running out and he said he didn't want to be separated from me. Immediately after marriage, all he cared about was the immigration status. Once that was taken care of, three weeks after marriage, the physical abuse started, I discovered his girlfriend and for both reasons, kicked him out of the house. He told me if I didn't go through with the immigration interview, they would put me in jail for marriage fraud. Two weeks after the immigration interview, I sent in a letter to withdraw my financial support, but USCIS say they never received it. When I filed for divorce after 8 months of marriage, I discovered I'm financially responsible for him because of the I-864.
Last time I talked to him (two months ago), he said he was "desperate." So, I'm caught between fear that he'll retaliate if I tell USCIS and fear that USCIS will throw me in jail for marriage fraud if I don't. Other than changing my name and moving to another state, what can I do?
