My husband and I are both F-1. File 1040NR separately. My son was born here and has SSN. My husband filed 8901 for the qualifying child but was rejected this year. He wrote to IRS twice and didn't hear back. We called and they mailed me something like list. Didn't say rejection of our claim. But seems that they did receive our letters and did a recheck. Still didn't give us the $1000 credit.

How can we do now?
