I would say make sure how open she is to your culture/family. A marriage cannot succeed for Nepalese or will be a very strenuous one if one of you are not open or accepting of other's culture/family.

Make sure she meets your family several times if possible before making the final decision.

Can she handle you with your family?

Can you handle her with her family?

Check out the whole package and not just her because once the glow of love fades away, you will need all these support systems to hold your marriage. ANY marriage for that matter.

Thanks!
