I was denied political asylum 3 years ago and the judge started removal proceedings,at the time I was dating my husband for a year already so he insisted we get married right away without waiting any longer. Now after 2.5 years of marriage we finally have interview for I-130 scheduled, can I still get deported? And how can I prove that relationship already existed at the time of my sad immigration court experience?

You need an experienced immigration attorney to assist you.

If you are already in deportation proceedings, the I-130 can be approved by USCIS as they have jurisdiction over your USC husband, but the Immigration court has jurisdiction over you. After the I-130 is approved, the I-485 AOS is filed with the court and approved by the IJ.

You will prove up the bona fides of the relationship with documents proving cohabitation and co-mingling of funds, as well as your sworn testimony at the interview and in court. Good luck.
