As you wait for your LSC, Cradle of Hope team will help you to complete drafts of Form I-800 (Petition to Classify Convention Adoptee as an Immediate Relative), Form I-864W, and Form I-800 Supplement 1. This is done ahead of time, so when the LSC is received, these forms are ready to be submitted (by CHAC) to the United States Citizenship and Immigration Service (USCIS).
The I-800 is very similar to the I-800A, the application you filed with USCIS prior to submitting your dossier to China. The difference is in the request. The I-800A requests approval of you as prospective adoptive parents, to adopt a not-yet-selected child with specific special needs. The I-800 requests approval to adopt a specific child.
After CHAC submits the I-800 and its accompanying documents, I-800 approval notice typically takes three to four weeks to arrive. The I-800 approval means that your request has been approved and that your specific child is eligible to receive an immigrant visa. Once approved, you can move onto the final major step of the process, Article 5.
