Previously raised questions are certainly allowed. Mentioning previous answers are intended to be a starting point, not to discourage discussion. Follow-on questions, data, and debate are welcome.

I PMed to ask what "get to" meant: "visit" or "emigrate to"? I just got an answer: "Either".

For legal emigration, I find "Could you, legally, leave East Germany for West Germany?" at https://www.reddit.com/r/AskHistorians/comments/5peclu/could_you_legally_leave_east_germany_for_west/ , with answers by /u/thesaefkows_css and /u/kieslowskifan .

Also for legal emigration, there was some sort of "selling" of people by East Germany, paid by West Germany, but not a lot of detail there. "Why did people try to defect over the wall in Berlin and not through some unguarded part of the huge border between East and West Germany?", under https://www.reddit.com/r/AskHistorians/comments/2luour/why_did_people_try_to_defect_over_the_wall_in/clycyfi/ , SirGuyGrand and Poebbel here.

For visiting, there's an FAQ item at "What was life like in East Germany before the Wall fell?" at https://www.reddit.com/r/AskHistorians/comments/13b6xt/what_was_life_like_in_east_germany_before_the/ . In a much longer and informative reply, /u/BruceTheKillerShark wrote "Eventually, the GDR relaxed its border controls to a certain degree, mostly allowing West Germans and other westerners to enter East Germany, while occasionally authorizing East Germans (particularly in Berlin) to leave the country for visits to the west."
