One looking "jewish" does not mean is a jew. One looking like an aryan top model does not mean either is not a jew. Unless one knows factually they are a jew, they should not come here, and this is by family, traditions, parents practicing Torah or going to synagogue, knowing your parents are jews. Unless this happened, one should never worry and one must get to connect with our Gods and have civic duty towards the expansion of the Temple. Even these jews who want to beg Zeus, sorry, yes, you will never be accepted, but you should try clean your sins as much as you can, and support the Temple and betray your rabbis.
