Has anyone else had difficulty recently in successfully delivering the U.S. Social Security Form 7162 to the SSA p.o. box in Wilkes-Barre, PA? Some months ago, I (like most other U.S. retirees) received the form, signed it, and put it into Thai Post EMS. With tracking I could note when it reached the U.S., but there it sat in "international arrivals" or some such designation, just collecting dust. Thai Post did fine; but the pathetic USPS simply lost the envelope or just gave up.
Now, of course, I've received the "second notice" from SSA, and now after the month(!) it took to arrive here, I now have 15 days to get this second one over to them in Wilkes-Barre. Has this happened to anyone else and, if so, what deliverly method did you use? I understand that the couriers (DHL, FedEx, etc.) will not / cannot deliver to post office boxes. I have actually found the physical address of the SSA in Wilkes-Barre and am wondering and considering courier-ing it to the office rather than the po box. Thanks for any help from anyone else who has run afowl of the bumbling USPS.
