Is it permissible to introduce a Catholic woman to Islam, and what are the best available methods and means for doing so, taking into account the questioner's weak English language skills?

We thank the questioner for his eagerness to invite people to the religion of Allah. There is no harm in continuing to invite the aforementioned woman to Islam, while adhering to the limits of Sharia when corresponding with her or speaking to her. Islamic website addresses in English can be sent to her, and assistance can be sought from preachers who are proficient in English. Remind him of the Hadith: "For Allah to guide a single man through you is better for you than red camels."
