Actually, the support test doesn't really apply, since payments from state do not count as child providing over 1/2 of their own support. That's what I was thinking, but hadn't found verification of it before I posted. |From Pub 501:
Example 2.
You provided $3,000 toward your 10-year-old foster child's support for the year. The state government provided $4,000, which is considered support provided by the state, not by the child. See Support provided by the state (welfare, food benefits, housing, etc.) , later. Your foster child didn't provide more than half of her own support for the year.
