euta ta america ma nepali keta ko sankhya keti ko bhanda dherai chha, so naturally ratio mildaina.
arko, keti manchhe haru jo jo aaka chhan student visa ma (bishesh gari undergrad), uniharu nepali circle ka keta haruko giddhe dristi bata bachna hos ya bideshi muluk ma sangharsha lai sajilo banauna hos ya aru kunai karan le hosh, euta bf banaune tendency maximum hunchha. So single kt nai bhetina garo chha nepali.
Single keti nai kam bhayesi, demand and supply ko rule anusar thorai nepali kt jo single chhan uniharuko bhau aakasincha.
cast, religion purba paschim, valley ko ho ki valley bahira, nepal ma dad mom ko status kasto, yi sabai BS ta nepali haruko ma chhadai chha.
arko kura us aayera 2-4 barsa yahako life dekheka kt harule keta ko status, income lai badhi nai priority dyeko dekheko chhu maile.
keta le ni aafu jasto financial/legal status ma bhayeni "chwak" keti lai lastai priority dinchhan.
Mathika sabai karan le us ma nepali keti bhettaunu sarai garo parchhan.
tyasko thyakka ulto nepal ma, us gako keta bhanera limited family bahek dherai le ali badhi nai mahatwa dinchhan.
dherai keta haru bidesh (khadi, austrailia, us, etc) gako le nepal ma keti ko sankhya ketako bhanda dherai chha. So obviously nepal ma keti dherai available hunchhan, bf ali thoraiko matra hunchha, or bhaye nai pani dherai serious chhaina bhane US bata aako keta bhanera bf lai bal dina ni sakchhan.
Sabai lai generalize garna or blame garna khojeko hoina, dekhe suneko kura.
