Just petition using a I-130 yourself. Read the instructions very carefully. I am not sure but itu2019s possible that the affidavit of support will need to be filled by your husband since he is the citizen and he filled one for you - again, check the instructions very carefully. It should be a pretty clear, straightforward process.Your child is still well below the age limit and should be fine. If there are any problems, do the same thing you did with your own process - use the numbers you are given to check on the process and if you see it stuck call to make sure they have everything they need early.It is my understanding that the age limit of the child is based on the petition date, so go ahead and do it.You still have plenty of time at 16, just donu2019t delay.
