I fell in love with a woman from Serbia

I fell in love with a woman from Serbia, living here undocumented. Left her country after being attacked for being gay. Came here on a work visa. The visa expired, she continues to work here and pay taxes. She can not get health care coverage. We have paid nearly $10,000 and have waited for more then two years to try to get a green card, still waiting. We wait, we live with anxiety, hope she will be welcomed here legally sometime soon.
