No, they are not US citizens. We've been living in the US on a TN visa for the last 3 years. They received the SSN last year as part of the immigration process (not finalized yet)
I'm honestly not sure what to put in the tool given this special situation. Last year I was able to deduct 500 per child because they only had the ITIN (same as the previous year, where my taxes were filled by an accountant firm). I surely messed with something this year because the tool is telling me that I my total deduction per child is 0.
