The research rule
Move closer to the decision maker
Start with the law, regulator, agency, embassy, program authority, or provider that controls the issue. Save what you relied on. Recheck before paying, applying, signing, or moving.
Good research does not eliminate uncertainty. It makes the remaining uncertainty visible before it becomes expensive.
