Thanks XBT, still not clear

I got the written notice already, it generally said at the very beginning"All documents are to be in the original form accompanied by a copy..."it didn't say individually.The checklist is rather long, like
1. Birth certificate issued by competent authrity in your country of birth.
2.A copy of approved form I-140, with all attachments(a friend of mine who also had an interview not long ago told me the attachment here means all documemnts you filed with CIS, including all awards cetificates..)it didn't say individually.
What I should do next???
As you know, BC is so difficult to get, because I am over 40,it will take a long time, it will be costy...
