A US resident alien must have a green card or pass a "substantial presence test". However, the tool says that my children do not qualify for dependent tax credit. Why?

I also noticed that this year the tool has an extra selection for "Mexican and Canadian citizens" besides "US citizen and legal resident" and "none of the above". At this point I don't know if it's because the tool is broken, or if a new specific clause was added.

You can claim a non-citizen child as a dependent if they meet the IRS definition of a "qualifying child" and have a Social Security number or ITIN.  If your children don't have an SSN, they won't be eligible for the Child Tax Credit, but will qualify for the $500 'Other Dependent' Credit. 

The Mexico/Canada citizens selection is not new, however.

Thanks. I went to the IRS website, went through all the questions and confirmed that they should qualify for Child Tax Credit. 

I will try clearing the cookies. If that doesn't work, then I'll have to contact support
