Dependent NEC1099 and dependent status

My son is a full time student in college, aged 22, and received an NEC-1099 for $2000 for a college related job. This is his ONLY income. My husband and I pay all his expenses so far. We have always claimed him as our dependent.

 

-I believe he has to submit his own taxes this year for those $2000 earned, correct?

-Should my husband and I still claim him as a dependent in our own taxes? Or  not?

 

Thank you in advance!
