I have a 30 year old divorced ( 2 years) step daughter and 4 year old grand daughter. My wife is here is the US with me still on her 2 year conditional green card. We would like them to come live with us. Can we apply for them now? If yes who would apply me or my wife. We would of like for them to come for a visit but guessing that's out of the question being she is single and 30 and getting them a visitor visa is so slim. She is a business owner and owns her own home if that even matters . She wants to be close to her mom. Any advise or suggestion would be appreciated.
