My Uncle apply for us 15 y ago,Now mother named only get letter from NVS , to pay fee for Interview. we are married now, what about us.

I suggest that you find some other way to immigrate. Your mother will have to become a US citizen in order to begin petitioning for you. For US citizens petitioning for married sons and daughters, the process is taking approximately 12 years. When added on to the five years for her to become a citizen, it hardly makes sense for you to attempt to immigrate in this way. You and your brother should try to find another route.
