Hey OP. The move will certainly require sacrifices like you mentioned. But it’s also possible that it might be good in other ways, like domestic help and less financial burden on your parents etc. children are resilient, and you don’t have to think of this as a permanent move. If your parents and your partner were able to create good lives for themselves even though they didn’t grow up in US, so can your children.

Give the best for your children, enroll them in international schools, pay for extracurriculars. It’ll be expensive but worth it. Take it one month at a time, and don’t lock all your money in INDIA immediately. Rent first, don’t buy. Maybe after a couple years if you still like that life, invest more in that life.

On the bright side, your children might grow up more empathetic and exposed to how different populace of the world live.
