Hi rameshprabhat . Mathika suggestions harulai maddhya najar rakhera malai pani 2 4 shabda rakhna man lagyo. If you are really stingy then you can save couple hundreds dollar every month. I do not know how desperate you are? If you eat TOP RAMEN ( nepal ko rara chauchau jasto taste bhayeko) everyday then you can save more than $500 a month. Regarding the greencard , right after you come here start chasing those fat ass bitches then you will get green card soon if not then you might have to wait for another ten years or so. good luck.
