First of all, just asking a hypothetical questions. No offense to Jewish people and their culture/religion.
Let’s suppose there is an Asian guy who can study Jewish culture/religion very well and decides to convert, not because he believes in Judaism but in order to immigrate to Israel. I know that procedure is tough(I am already curcimcised), but it must be possible. If after that I l will become a Jew(and of course there are people to become Jews), I should be able to use the rights that other Jews have, right?
Then, if this works, why not poor atheists from other countries at least try this to have a better life?
