if you have got into Hass and are able to afford it, grab it with both hands

If you really have gotten haas , you won’t be asking this question

I will not commit any mistake for choosing haas mba over Columbia right?

MBA

MBA is costlier but better for getting a job in the US.

I keep stating ad nauseum LLM is not a qualifying degree on its own, so legal jobs in a different jurisdiction (to where you did your LLB or qualifying law degree) is always difficult to get.

Which will be better for settling in the US?
