Yes, i'm planning to do that.
Very good. Then you must proceed including the SSN in order to match it with the correct application. I must remind you to not write anything on the original documents and to write your SSN in a separate sheet and then include it in the mailing envelope.
What about if i decide to not send these documents? There's an option?
Indeed, there is. I f you don't want to mail your documents, just bring them yourself to the Social Security office.
