Adopt from Foster Care or Internationally? Or Both?

Although I am still a couple months from getting my foster care license and about as long from making a firm commitment on adopting internationally, I am still wrestling with how to proceed.  My issue isn't so much whether I'll do either of them but in what order should I do it?

As I've written before, internationally adoption is an expensive proposition.  It can easily cost between $20,000 to $30,000 with an agency.  The other complicating issue is that Haiti, in particular, will not let you have children in the home.  This would seem to preclude foster to adopt while waiting for the Haiti adoption to go through (which could be several years).

By the same token, I know there are many children waiting for families here in the US. It seems silly to wait (possibly years) when there is so much need.
