Ok. i'll get into it. Now, can i apply for these benefits even if i'm outside the U.S?
Sure, no problem with that. All you need to do is to contact the nearest U.S Social Security office, or go to your nearest U.S Embassy or consulate.
Soryy to ask, but what was that section you mentioned in case to be never married?
Yeah, don't worry. That would be How to apply for retirement benefits or medicare section.
