I don't think Ethiopia allows singles to adopt anymore, although they might make an exception for older children or special needs children. Check out the country guidelines on
RainbowKids.com Adoption Information, Support, Child Photolistings, Articles and Resources and also go to the U.S. state department's website at
www.usdos.gov & look under intercountry adoption. I think all of the countries do require the adopting parent to travel but some require much shorter trips than others.
