to complete the legal process. Some countries allow a child to be escorted to the adoptive parents' home country and the adoptive parents are not required to travel to the country of their adopted child. There are usually several requirements after this point, such as paperwork to make the child a legal citizen of the adopting parents' country or re-adopt them. In addition, one or more follow up (or "post placement") visits from a social worker may be required—either by the placing agency used by the adoptive parents or by the laws of the country from which the child was adopted. In the United States, citizenship is automatically granted to all foreign-born children when at least one adoptive parent is a U.S. citizen, in accordance with the Child Citizenship Act of 2000. Depending on the circumstances of the adoption, the grant of citizenship takes place upon the child's admission to the U.S. as an immigrant or the child's adoption in the parent's home jurisdiction. Policies and requirements Adoption policies for each country vary widely. Information such as the age of the adoptive parents, financial status, educational level, marital status and history, number of dependent children in the house, sexual orientation, weight, psychological health, and ancestry are used by countries to determine what parents are eligible to adopt from that country. Information such as the age of the child, fees and expenses, and the amount of travel time required in the child's birth country can also vary widely from one country to another. Each country sets its own rules, timelines and requirements surrounding adoption, and there are also rules that vary within the United States for each state. Each country, and often each part of the country, sets its own rules about what will be shared and how it will be shared (e.g., a picture of the child, child's health). Reliability and verifiability of the information is variable. Most countries require that a parent travel to bring the child home; however, some countries allow the child to be escorted to his or her new homeland. The U.S. Department of State has designated two accrediting entities for organizations providing inter-country adoption services in the United States and work with sending countries that have ratified the Hague Convention on Protection of Children and Co-operation in Respect of Intercountry Adoption. They are the Council on Accreditation and the Colorado Department of Health and Human
