The warrant came to light about several months ago. I dont necessarily want to get into the details, but it is a felony level offense as I understand. The issue is I have not seen the arrest warrant. She has not wanted to provide it to me. I spoke with a lawyer in her home country, and although they can validate that she in fact does have an arrest warrant, they will only give it to her or if she gives the power to someone to go and obtain it.
As to whether it happened before she received her Visa, I am not sure 100% sure at this point.
I found this out from her, she was the one that told me there was an arrest warrant out for her...also several news articles came out in her country talking about the situation (does not involve just her), it was something several reporting agencies wrote about. In addition, as I mentioned, I had a lawyer I knew and had used before in the country who verified she has an arrest warrant.
I was and still am pretty shocked at everything honestly.
