I can imagine being harassed just because non you are an NRN and people assuming that u have a stash of dollar to throw around. I dont understand why you have to produce a paper saying you are no longer a nepali citizen as you already have a US passport. Cant u just sign a waiver or something?

My suggestion to deal with this person asking for money is to secretly tape him asking for money and then giving it to newspapers....Or just make an appointment with his supervisor and tell on him. If you are just trying to get a Marriage Certificate then may be go to a different court. Also try to do it through CDO of different city if your fiance is from another city.
