Yousef Munayyer, an Israeli citizen and the executive director of The Jerusalem Fund, wrote that Palestinians only have varying degrees of limited rights in Israel. He states that although Palestinians make up about 20% of Israel's population, less than 7% of the budget is allocated to Palestinian citizens. He describes the 1.5 million Arab citizens of Israel as second-class citizens while four million more are not citizens at all. He states that a Jew from any country can move to Israel but a Palestinian refugee, with a valid claim to property in Israel, cannot. Munayyer also described the difficulties he and his wife faced when visiting the country.
