I800 3/18/2012- United States approves us to bring specific orphan into our country. NVC 3/15/2012- National Visa Center approves paper work to apply for a visa for Mia. TA- 4/20/2012- Travel approval issued by China, allowing us to come into China to adopt Mia. CA- arrived 4/23- Consulate appointment sent out by the US from the US consulate in GZ ,China actual CA- 5/29/2012- This is the final step we do in China before bringing Mia home.
