pyaradeshbashiharu!!!!1 mind your language first. it does not make any different whether i am us citizen or nepalicitizen for you. now the point is let me know where are you now then i can give you better answer for that.

now gorkhethito! well you can sponser your parents and i think if you parents can incluide children's name until the age of 21 i think so... but not sure check with the www.uscis.gov. may be you can get more tips there. also

the best way is go through line by line instuction from uscis official web site which is very helpful. you will get lots of tips. i think you  did file your citizenship yourself. if thats true then you are smart guy i believe so go and follow the uscis guideline. there is nothing difficult to do that.
