because of a disability that existed before age 26

child’s date of birth. I have also enclosed proof of my regular and substantial support for my 

foster child such as: 

• Evidence of eligibility as my dependent child for benefits under other State or Federal

programs

I understand that I am required to immediately notify my employing office and my health 

benefits carrier if the child marries, moves out of my home, or ceases to be financially dependent 

on me. I understand that if this child moves out to live with a biological parent, the child loses 

coverage and cannot ever again be covered as a foster child unless the biological parent dies, is 

imprisoned, or becomes incapable of caring for the child due to a disability. 

Warning: Any intentionally false statement or willful misrepresentation relative thereto is a 

violation of the law punishable by a fine of not more than $10,000 or imprisonment of not more 

than 5 years, or both. (18 U.S.C. 1001).
