Can my mexican girlfriend marry me in the US after divorcing her Mexican wife?

My Mexican girlfriend (non US resident) got married in Mexico to another Mexican resident but is in the end of the process of getting a divorce. We want to start the process of getting married here in the US (which we know will be a bit harder since she’s not a resident) but we don’t know if her marriage and subsequent divorce will affect it in any way or prohibit her from marrying me. Of course we’d be waiting for her divorce to be final. But we wanted to be sure we wouldn’t run into any issues afterwards. More info: She’s here in the US now, her soon to be ex-wife still in Mexico and finishing up the divorce. I’m a US born citizen but also a Mexican citizen as well as my father was born there. And I’ve never been married.
