Well it worked,

my social security payments have been moved from my US bank to my German bank.
What a procedure. Most of the issues involve security. They don't want you to just change bank deposit on-line.
It has to be mailed in and then you get a call from a person at the consulate near you. You need to sign into MyID to show you are you.
Fun stuff, the man I talked to was great and we got it done. The first attempt sounded too much like a scam, Unlisted number with no call back, wanted a pin, and other personal information. So I hung up. Had to call the consulate during the hours that they work on SSocial Security. All is good.
