Thank you. On this website, I do not always get to give good news, and this is one of these times.
Under current law, your children do not gain automatic US Citizenship
though the father because he himself is was not a US Citizen at the time of their births. This is true even if he gains citizenship later on.If
he petitions for your family, then you and your children would get lawful permanent resident
status (greencards). You can then petition for citizenship in a few years after living in the USA, as well as your children. But HE has to file for this - you cannot make him.
Please note: If I tell you simply what you wish to hear, this would be unfair to you. I need to be honest with you and sometimes this means providing information that is not optimal. Negative ratings are reserved for experts who are rude or for erroneous information. Please rate me on the quality of my information; do not punish me for my honesty.
I hope this helps and clarifies. Please use the SEND button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of THREE OR MORE STARS and then click FINISH to submit that rating, as this is how experts get credit for our time. Rating my answer the bottom two stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating (it does not cost anything extra to rate).
