How does the federal adoption tax credit work with international adoption?

Can you answer this member\’s question?…
I know that we would need to spend the 11,000 or so in adoption expenses in order to get that matched in credit, but how does the tax credit actually work? If we fill out our taxes and we are getting a refund of say $500, do we get the credit on top of that or do we have to owe money in order to receive any of the credit?
