How long is the wait to adopt a child? This is a complex question to answer!
Why?
Because your total waiting period to adopt a child depends upon many factors, including the race, age, health and nationality of the child, whether you find the child yourself through a private source or whether you work with an agency, the specific agency you select, your level of motivation to adopt, your total adoption budget, and (in foreign adoptions) your willingness to travel.
In general, healthy Caucasian newborns and infants are the most sought after children and the wait for these children can be many months to many years.
If you are willing/desirous of adopting a Black, bi-racial, or multi racial child, the wait may be much shorter - only a matter of a few months.
A special needs child, e.g. an older child, or a child with physical, emotional, or intellectual limitations, can often be adopted through special county, state, or private agencies in a relatively short period of time.
The waiting period for foreign-born children usually depends on the specific foreign country the child is adopted from and can vary from a few months to a few years.
.............................................................
Don't forget that adopting a foreign born child may involve significant travel. While some countries allow you to adopt the child and have the child escorted to the US, others require you to make 1 or 2 trips to the foreign country.
And don't forget your total waiting period will include the several days, weeks, or months you have to stay in the foreign country.
The best way to find out how long YOUR specific adoption will take is to write down all your questions. Then personally call the agency, talk to the staff, and have all your questions answered.
