I phoned my local SSA office in Chicago and they sent me a short form to fill out via e:mail. I entered my new USA address on the form, returned it, and a few days later I was able to open the account using my new (daughters) address.How did you notify them? Did you call them, send a written letter, send an email? And which office did you notify?
If you get SS and are unable to change your address online right now, you can call SSA at 1-800-772-1213, Monday through Friday from 7 a.m. to 7 p.m. and they will take care of this for you. The other option is to get the phone number of the SSA office in the city where you previously lived in the USA and call them. They will in-turn send you the short form to get you rolling.
I suggest doing this type of change through SSA USA versus Manila.
Hope this helps.
