According to Israeli citizenship law, tyhere are several ways of becoming a citizen.
1- Being born in Israel BEFORE Israeli independence in some cases. Druze, Armenians, Circassians and others got it that way, and so their descendants. Just because they were considered long term naturals of the land and had no other nationality.
2- Being Jewish (or a Gentile with at least one Jewish parent or grand parent), if the Jew (or the Jewish grand-parent has not rejected Judaism, and the prospective citizen establishes his/her residence in Israel. Those citizens are allowed to keep also the citizenship of origin.
3- Having legally resided in Israel for at least 3 of the last 5 years. In that case, a Gentile could theoretically apply for citizenship from abroad without even going to Israel, but he/she has to irrevocably resign the former citizenship. It's because they assume that a Gentile who resigns his citizenship is seriuosly planning to settle in Israel.
4- Having an Israeli Parent (no matter how that parent became a citizen) at time of birth, even if born abroad. Only if the parent got him/herself naturalized or born in Israel. That is, a child who is born abroad to an Israeli citizen is an Israeli, but he cannot pass his citizenship to his own children. However, as any other person, that children could get citizenship by Law of Return if they are Jewish or kins to a Jew, or by residence in Israel if Gentiles
Apparently, that girl is going to get her citizenship by naturalization on the basis of legal residence. If it's just a personal preference to live in Israel and abide by Jewish Soveregnty and Authorities, and it's an isolated personal case, I have nothing against it. But I would oppose a mass of Gentiles naturalising in Israel. We have plenty of lands in our Gentile countries to settle.
