While you can make the certificate the way you want if you have links to VDC/municipality, but the US immigration system knows about birthe certificate in Nepal. So i suggest you make one as it is the way any VDC/municipality provides and translate it to English.

If you look at the birth certificate part, toward the end it says the birth certificate is in printed form where birth info are handwritten.
