What you have in Nepal and not in US, if your family, your parents. Every moment spent in US is moment not spent with them. As we struggle here in the US, our parents age in Nepal. And before we know, they will have died. And it will be too late to regret. Then any motivation to go back to Nepal will be worthless.
I moved to the US when I was in my late teens; I was excited about my new life and did not bother to look back and think about my parents. Now it's been 12 years in the US, and each time I think about my parents. Each time I go home to visit, I see their wrinkled face and greyed hair. And I see it more and more during each visit. Before they used to tell me that there was no point coming back as Nepal has not future. But today I can feel that their sentiment has changed. After 12 years, they miss me as much. They must wonder if I will every be back to spend time with them during the last stages of their lives. And brining them to the US would be like uprooting a well grown plant. It will just dry and die off in a new soil.
So this is where I am today; go back to spend time with the most imporant thing in life or stay here and hold on to the comfort and some money but all alone.
