If the following two sentences are correct, do they mean the same thing?
1) You must come round (to my house) sometime soon.
2) You must come over (to my house) sometime soon.
Thank you.
They are both correct, and they mean roughly the same. In this sort of context, "over" and "round" have somewhat vague or variable connotations of closeness, familiarity, or intervening features to be crossed/navigated. For example, if the other person literally just has to cross a street to get to your house then you might tend to say "come over".

In US English, 1) would have to be "...come around...". The meaning of the two sentences is the same, but 2) is friendlier-sounding than 1). Also, 1)'s house would typically be farther away than 2)'s.
