If your wife and stepson's still has good non-immigrant status, they can probably do so, but they should keep all papers you have filed for them. Have you also filed the I-485's Just approval of the I-130 does not give the beneficiary legal status in the US.? If they are not legal, there are concerns.Why does your wife and step-son have to go to New York? Especially if New York is not your home state. If your wife does not have legal status and/or you have not file the I-485, you better go see a good immigration attorney.
