Last September, Democrat Representative from Washington State, Jim McDermott introduced HR 5947, the Improved Employment Outcomes for Foster Youth Act of 2016. That bill died with the passing of the last Congress.
A similar bill has now been introduced to the new Congress.  H.R.2060 and S.885 were both introduced to their respective chambers on April 6, 2017. While the text of the new bills is not yet available, both of their titles state that they would “amend the Internal Revenue Code of 1986 to include foster care transition youth as members of [WOTC] targeted groups.”
See my post from last September for detailed coverage of the original bill.  My guess is that the current bills are very similar.
