I am an US citizen. I am applying for my brother. He is single right now. But I am sure when his application (Family F4 preference) becomes current in 12 or so years he will be married and possibly have children.
My question is, what happen in 12 or so years. Will my brother get to bring his family with him. Or will he first have to immigrate and separately sponsor his family to come to the USA.
My brother plans to get married next year. Should I wait until after his marriage so I can include his wife in my I-130 application?
Thank you very much.
