Hi all..I'm just a new member here. I would like to ask since our grandmother file a petition for my mom and I'm part of it. But I'm over 21 y/0. Can I still come with my mom and dad together with my bro which is under 21 y/0? If not How many years will it take for me to go there in US? I'm still single now,Does my mom need to file a separate petition for me or since I'm part of that case number,there's no need to file a separate petition? If after the petition is file for me and after a year I got married,Does my child and husband can come with me? Please let me know the process

Once your mother gets green card, she will have to file the petition for you.

How long would it take for my mother to have a GC?

How long would it take for my mother to have a GC?.Is it 6 months only? Should I wait for her to be a US citizen before I get married? or I should be single for her to petition me? Just in case I got married by the time that she file a petition for me will it take several years for me to go there or It would be easy for me to stay single by the time that she file a petition? Please let me know the process and the important details. Thanks
