Evidence I'd gathered years before I even knew EB-1A existed — how I used it

Had accumulated a fair amount of professional documentation over the years for entirely unrelated reasons (performance reviews, project reports, old award certificates I'd nearly forgotten about) long before I ever started thinking about immigration. Sharing how I approached mining this older material once I started building my case. Going back through years of old files was tedious but genuinely worthwhile — I found a couple of pieces of real, usable evidence I'd completely forgotten existed, sitting in old email archives and a long-neglected physical folder. Not everything old was usable (some documentation had gaps I couldn't fill retroactively, like missing context I no longer had access to), but the exercise of a genuinely thorough archaeological dig through my own professional history surfaced real material a more recent-memory-only search wouldn't have found. If you haven't done this yet: a dedicated pass through old email, old files, and any physical archives from earlier in your career is worth the tedium — you may well have relevant evidence sitting forgotten that would take real effort to reconstruct from scratch if you didn't already have it.
