Hi, Sugareeka
I have bunch of friends who chose to go back to Nepal despite finishing their degree here in US though they had h1b and options for AOS. They are doing just fine in their respective fields and are not regretting at all for their choices. Just be strong, sometimes life does not go as we plan and going back to Nepal and starting from scratch does not mean failure at all, its a Resilience. GC/Citizenship gives a hope for better future but does not guarantee success and happiness. If you have a positive outlook towards life, you can be happy in any corner of the world.
Best wishes from another fellow nepali woman :)
