thank you for your advice sir i have a follow up question if i m going to petition my wife and daughter while i m immigrant do i need to wait 10 years as green card holder before i can petition them?thank you in advance..

No. You can petition for them immediately. You will give yourself the most flexibility and options if you file separate petitions for each of them since if you become a citizen before they immigrate that would affect the process. Consult with a lawyer who will explain in detail and help coordinate everything.
