Hi i always regret in my life about not joining Mavni when i was a student! I was scared of being put on wars in Afghanistan n Iraq! But when i realized college is not worth i wanted to join but it was closed! I thought it will never open n i became out of status! N it was opened! I eventually married a white gal n gig a green card now! But i feel like i am late as all my frens got citizenship before me like around 2015! They traveled ti Nepal already several times! But i am traveling soon after 20 years in America! I feel like i missed out lots of stuff which is time as time will never come back! Now i even feel like give up my green card! So u know regret comes as if i had a citizenship just like mg frens before i might have been different like energetic n wanted to do something in my life! Now i dun feel like doing anything but to live in Nepal as a retired man!

Are you taking your wife and children if any with you ? Are they willing to go ? It seems you married just to get green card only. Do not compare to you friends and family where they are and what they are doing. Everyone has their own strength, dedication, focus and success. You are inviting and creating sorrow focusing on your friends achievements.
If you are so much jealous of them it is your turn to do something rather than running away from your own created problem.
Even Going to Nepal will not solve your problem.

Well, better late than never. At least, you should be happy that eventually you have a greencard and there are some who does not have an opportunity of getting one. Sooner or later, you would also get citizenship and now you can visit Nepal on your own will and time since you got a greencard.
I think you lucky dude :) @shekhar143
