Hello Login, yes you need to get a invitation letter from your international office's adviser and send it to your parents. You don't need to send those passports, transcripts and shits! A letter from internatioanl office is enough to replace your transcripts and your status! But, most improtantly, make sure that your parents would show the bank balance from Nepal. I think these khaire's now wanna see people from Nepal to travel with their own money from nepal rather than your dollar that you have saved in your bank here. Baru Nepal ko tanna paisa dekhauna launus, that will work.........Khaire haru ko ni arthatantra ma sukkha jo lageko chha.............. Also, ask your parents to make a letter from municipality office stating that you are their son or daughter or whatever.......... Hope this information is useful for u......
