May be I can relate little bit on this. My brother is married to american white with one kid for 14 yrs now. I am married to nepali after 5 years of live in.

And my conclusion is very simple and short. Non-of these suggestions and story really matters. All these stuffs are completely identical to you and spouse personality. No one will ever be able to make any judgement then your self.

Regarding nepali gals being honest, I seriously doubt that, may be gal from good american family is more honest after marriage.

But I will definitely warn you against any foreign marriage if you are in traveling job. By the way my Bhauju makes best dal, bhat & achar even though she doesn't eat it much :)
