thanks! I finally was able to reach and speak to an agent...he confirmed that the docs were received, but he couldn't see if they were attached to the app. But later in the evening I received an email which states:
"...We are pleased to confirm the reception of your document. We have forwarded it to the responsible office for their consideration. If further information is needed during the processing of your application, the responsible office may contact you."
So I guess they received my docs....but didn't attach them yet. Am I right? But anyway they have it - that is what matters
