In My case, I brought my x-wife in the States, Spent about 8 months together. She seemed more dmanding, didn't work out well that of her wishes increased largely like in American bitches.

I applied for divorce, and got the final decree in one year of the filing date.

It is a lot better to get divorce here in US rather than in Nepal. I am not aware of much of Nepal's divorce law, but as I have heard and folks are talking here, I am convinced  that you cannot get divorce from your wife until her consent to dissolve the marriage contract. This is absolutely, unfair, and biased law.

My suggestion would be, if you really want to bring her here (in US), don't even think of divorcing her in Nepal (which is more unlikely). Once she gets here, you both try working out. May be it will work, after sometime together and knowing each other in a better way, just like Syangjali Dai has advised.

If not, go for the separation process, for which you need to be physically separated for a year with no cohabitation (depending which state you reside) to be qualified the filing for divorce.

Hope this helps.
