Convert Having Problems Getting Married

I have been considering a young sister for some months now. She lives in another country and when I started talking to her it was through internet and on the phone with her dad’s permission. He said she was allowed to choose by what she wanted, wealth wise etc. and he would only care if he was a good Muslim and was practicing. Now, recently they were going to come here to meet me and we were going to get married. On the way here they met some family friends, who put doubts in his head saying she is not compatible (as an Arab) to a convert like me.

The question I guess now is that I am going there and I and she have both done istikhara awhile back and it came out very positive. She was hafiz since very young and I love Islam and Allah and have been learning Islam since I converted. Both of us got positive istikhara’s and were marrying for the deen etc.

If I go there to them and her dad says no because I am too young (21)… or says things like I am not wealthy enough etc. (I do have a job and my own house and support just fine but I am not well off at all but am stable enough to support a wife inshaallah)… or other reasons such as those what rights and options would me and her have? We really want to marry…
