Once we have a mass exodus of Neps into the US some fine day into the future, and we end up having a few million peeps here then the Nepali accent would surely not seem outta the norm anymore.  Damn, we've come into terms with Ebonics and Spanglish (can hear Hispanics call each other "stooopid" ever time I ride the 7 to Jackson Heights), so who cares what is the right American way to pronounce words anymore??  Stick to pronouncing your words with the "ks" before the "sk" (decks instead of DESK) and also "sooj" instead of SHOES as  I or anyone out there could care less...We've much more to worry about than how someone else goes to a restaurant and orders "fiss" instead of FISH1

IMO, Just present your words with confidence as I could really give a damn about what anyone would think.  Confidence reeking outta you is what makes any "accent" out there sexay for the opposite sex!!!
