I have 1 biological child but am thinking about adopting in the future. Anyone adopt from Eastern Europe and know the adoption process and cost?
like Russia or the Ukraine?

It varies depending on agency. Here's some brief information from http://www.adoptive-parenting.com
# Russian children are matched with adoptive applicants by regional officials, and are placed directly from childcare institutions. Adoptive parents must travel to Russia to receive and accept their child referral, and then return to finalize their adoptions in the Russian courts.Before travel, adoptive parents will receive basic initial information about the child. Quick Facts: Must be married 1 yr.
# Boys & girls available
# Travel in Two trips
# Sibling groups
# Infants, toddler, pre-K
# Single women can adopt
# Estimated Cost:
$30,000 to $40,000
# Timeline: From completion of dossier to referral: girl, 6-18 months; boy, 0-6 months.

Russian Adoption assist families in achieving their dream of parenthood, but also fulfills the dream of orphan children in orphanages and foster homes who await the love of a family.
