The law of return is an Israeli law that doesn't actually leave much room for opinion and is not actually a definition of who is jewish.
It applies to all jewish persons whether through maternal descent or conversion as well as any children and grandchildren of such regardless of maternal descent and any spouses of eligible persons regardless of religion. It removes eligibility from those who had been jewish but have voluntarily converted to another religion.
This conflicts quite sharply with halakhic definitions who is a jew and even covers persons that would not be regarded jewish by today's reformist traditions that allow paternal descent.
Yes, but there is a giant debate in Israel right now about speedy-conversions, whether non-Orthodox conversions are allowed (at the moment, no), and all that that DOES affect the right of return.
