Thanks for the positive input. I hope you guys are right!
And no, I did not have an attorney. My brother prepared the documents for me. He is a legal assistant.
He told me to not worry because they cannot rescind the case unless they found something that disqualifies me. But naturally I am still worried.
Today I noticed the guy typed my last name wrong on the approval letter he gave me. He also CCed some attorney who I don't know. My brother said to wait for the biometrics to see my name.
How annoying!!!
