Parents do not get stimulus checks for children older than 16. If a college student CAN be claimed as a dependent then that student is required to state on his/her own tax return that he can be claimed as a dependent on someone else's tax return. Dependents do not receive stimulus checks.
The bottom line is there is no legal stimulus money for college students.
Parent do not get stimulus for dependents over 16. Any student who can be a dependent (whether actually claimed as a dependent or not) is not eligible for the stimulus on his own tax return.
Students who finished college in 2020 may or may not be eligible, depending on application of the dependent rules.
