A few steps closer but with a question

On May 18th I broke down and USCIS and found out that our I600 was being approved that day. I can honestly say that is when I started to feel it. Feel like it was ok, he is mine. I have a son. I have been hanging onto this fear and pain for 2 years now (as some of you know we tried adopting after Abigail and had 2 failed adoptions). I started to feel my heart and my trust opening just a little at a time. The next day we had our travel meeting. All went well but as usual I had a ton of questions. I started looking at places to stay, reading books and even trying to learn a little Korean. Now we were waiting on our visa approval. We were told wait 10 business days then check on the progress. So Friday I broke down and called at 6:30am. They had no record. All day I fretted. The mail arrived and guess what, we were in the system but instead of Joe's first name listed as Clayton it was listed as Slayton, also Nate's given name was misspelled. But we were approved and the Visa had been sent. So I called the agency but was too late, they were gone. So I am waiting til. Monday. It is only hours away but it feels like forever. Will this delay us? Will we travel sooner? So many questions when adopting.
