The Federal Benefits Unit in Guadalajara replied to my inquiry of this morning, confirming that, indeed, the Google information referenced above is old information. The FBU provided this further reply:
"Due to the current circumstances, the Social Security Administration is temporarily delaying the mailing of the yearly questionnaire forms SSA-7162 and SSA-7161 until further notice.
If you are currently receiving Social Security benefits, you should continue to receive your regular payments unless other circumstances apply.
If your benefits are suspended, please get in touch with us right away so we can verify the reasons and provide you with additional information.
Thank you"
