I just want to ask if you ever hired a lawyer in your adoption process?
Childwelfare.gov is a US Federal agency that has information regarding many different aspects of child welfare law and procedures. The link here goes directly to their adoption page. This is a site you will be likely referring to often Definitely start here to find info on adoption and check into their "by state" references for more info on Wyoming law and procedures.
Adoption.com is an adoption information service that has an adoption specific help forum. They say on their website that the do not deal with adoptions directly, they are an information resource for those thinking about adoption or going through the process. They appear to be US focused. Each state has it's own unique set of adoption rules in addition to the Federal laws governing adoptions.
Note that this site does sell adoption related products, so treat them as a "for profit" source that gives you the basics free, while selling items that make life easier.
If you end up going to a lawyer, start with the state adoption agency for a list of lawyers that they have found acceptable. The quality will depend on what the requirements are for getting onto the list, but at least they will all be familiar with local adoption law
May not be the answer to your question, but this will give you a start on understanding the process.
