How much will my get from VA if I go to foster care?

Junior, you only get what you need. Please provide more details.

Yes, a little more info. I am assuming you r under 18. Also, assuming any money coming to u will go towards your care while in foster care. You personally will get nothing as a minor.

Now, if you mean nursing care, you will need to contact the VA and see what ur entitled to. No one can answer that for u.
