Hi SKART

First instruction is relax a bit.

Is she too that determined to marry you. If yes get her converted to Islam in your country or in Q after getting all her required documents
. Once through that she shall follow Islam and you get married to her in legal religious marriage. The marriage certificate will be valid and you can bring her on a Husband visa.

alhamdulillah,

The harder the process and waiting to be together will only make your love stronger.
