You got a green card. Imagine. Now what is the drastic change you will bring in your life?

Not much. No more status related stress. Easy entry to US.

You’re 40 yo and you marry a 20 yo in Nepal 😂

You got Citizenship, what drastic change can be happening ? You can vote and get out this lunatic orangutan. GC and citizenship are only means only personal efforts bring changes.

less immigration and job related stress obviously. only them who went thru the process of getting green card will understand this. now you have a green card and good job you can bring your family here. family, job, with that job good life style, no immigration related stress what else do you need? you will be all set. but if you have good job, good money, family, big house but no green card that will still be big issue.
