All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
May Allah reward you for your eagerness to get married, and we ask Allah the Almighty to facilitate it for you.
There is no problem in the fact that this woman does not have a Muslim guardian, as the one who takes charge of her marriage in this case is the Muslim judge, or whoever represents him, such as those in charge of Islamic centers in those countries. If it is not possible to have a Muslim judge or someone who represents him, then she may authorize a just man from among the Muslims to take charge of her marriage, as stated by the scholars.
If Allah has decreed that you should get married, then we advise you to treat her kindly, to teach her about her religion, and to help her to stand firm on the truth. It is proven in the Two Saheehs that the Prophet said: “Treat women kindly.”
Allah knows best.
