Didn’t he have several? Did he travel to a “do not travel here” country using a foreign passport?
My wife made a comment once as to why no one could locate a normal BC. “Maybe he was born in a test tube”. She was joking ... I gave it some thought. Has anyone here read any or all of (ok laugh when you see this name) Dr Peter Beter ...? Yes, from “there is no gold in fort knox” fame.
Something about organic robatoids comes to mind ... hmm
Well, I don't know what passport he used, but travel to Pakistan using a US passport has been legal every day between August 15, 1947 and today, so if he used a US passport it would not have presented any problems.

There does not appear to be any evidence that he entered a country where Americans were not permitted to travel.
