Why would you try to cut corners? Your birth certificate should be prepared in a day. Add 3-4 business days for shipping. Total time: ~1 week.

I don't know if School Certificate can be used in lieu of Birth Certificate. I had the same issue as I did not have a birth certificate . I had the birth certificate issued from my ward. I had 2 copies made ( In English and Nepali). Anyway I did not get RFE using the document from the ward office. I guess just make sure its in the office letterhead with visible logo, phone number and address. Last edited: 09-Aug-17 11:50 AM

I actually got a RFE in regards to using the nepalese version of the birth certificate in my original applicatin. So, I had to get a new one with the nepali and english version of the birth certificate from Kathmandu Metropolitan office. It seems they provide that these days so good for us now. I don't recommend you to submit it without getting the english 'birth registration' document from the Kathamndu or whichever district your's applies to in Nepal.
