So back to the issue at hand, I have a new tax client who has lived in the US since 2015 (work visa) and has a SSN.   Wife and kids have ITINs.   Wife and kids moved back to their home country in 5/2019.   My client can still file as MFJ, but the kids don't qualify him for the $500 'other dependent' credit because they lived with my client less than 6 mos.   So, I have to check that box that they don't qualify, correct?
