My fiancé came to the US (Los Angeles, CA) on 12/25/19 from Armenia on a K1 visa that expired on 1/2/20. We have until 3/23/20 to get married and apply for a green card for her. Only family she has here is a maternal aunt and a maternal grandmother. When she got here she was staying in a separate room in my house. After several days of endless arguments we decided to break up. On 1/8/20 she packed her bags and her aunt came and picked her up and took her to her house, where she’s currently staying. I don’t think she’s the right person for me and I want to put an end to all this. I don’t know how to go about it. We haven’t submitted any documents and haven’t filed any forms with USCIS since she’s arrived. I also don’t want to be medically, financially, nor legally responsible for her if anything happens to her moving forward, since we’re no longer together. Are there any actions I need to take at this time? Any forms to submit to the government? Any authorities to notify? Thank you.
