Interesting use of the word "should" in the passage quoted above: "...you
should request that individual’s PRIA records from the foreign carrier
."
Well, because the FAA thinks of everything, they have actually devoted time and effort to defining their use of the word:
Should = recommended
These are the only valid word choices to convey those meanings.
