Besides the generally accepted halakhic definition of who is a Jew, the Law extended the categories of person who are entitled to immigration and citizenship to the children and grandchildren of Jews, regardless of their present religious affiliation, and their spouses. Also, converts to Judaism whose conversion was performed outside the State of Israel, regardless of who performed it, are entitled to immigration under the Law. Once again, issues arose as to whether a conversion performed outside Israel was valid. The variation of the definition in the Law and the definition used by various branches of Judaism has resulted in practical difficulties for many people.
