UI- I  think is an IRS issue not INS.  They might ask you about your job etc etc but as long as you are a law abiding person with all the eligibiligy for a Citizenship, I dont think UI will stop you.  Besides where does Neptex/Nepali dai get his facts from?  Can you guys enlighten us and quote them please?  On matter like citizenship please also consult your lawyer you dont have to believe what is said here.
