Ok this could be a sensitive question, so someone feel s offended i gonna delete it, but if Yemenite Jews had contact with Indian jews, why they dont migrate to India where there wasn’t opression against them?

Hello guys Hindu-Pagan here, i was reading about Indian jews and say that they remain in contact with jewish world thanks to yemenite jews, who had a situation that was… less good, but i was thiking, if yemenite jews were in contact with a jewish population that live in a no-antisemitic territory why they dont migrate with them? After all Ashkenaz jews do it to Poland Commonwealth for European antisemitism
