That is correct. Those documents involve to prove your citizenship, you U.S citizenship.
Do you have the documents, or not?
No, no, i don't have'em
Unfortunately, no relevant information is found.
Am, this i think i know the answer but i've been living outside of the U.S for long time, what would need then?
Well, in those cases, you would need a current or previous passport, school or employment records and any other records that show your long term stay outside the U.S. That would help to show us that you don't have a SS number.
So i have a broad option, isnt? Any document will do it, always it can show a proof of my residence outside?
Outside U.S, yes. But remember those documents must be original.
Maybe the Social Security benefit you listed is exactly what I require. Will I be able to get money right away if I did that?
The benefits will be sent to you starting on the sixth full month from the date of your disability.
All of this seems so difficult and overwhelming. Is there anything that can make it easier for me to understand?
