> The average level of American "OMG so excited to meet you" is usually reserved for actual celebrities in Europe
I've been an American all my life, and I've never seen anyone say they were excited to meet someone other than either an actual celebrity or someone who has been significantly talked up in advance to the level of being at a quasi-celebrity level in context (and even in the latter case, “I'm glad to finally meet you”, possibly followed by an explanation of the reason they've been looking forward to it, is much more common than expressions of excitement.)
Honestly, the behavior you seem to be describing is one which would strike most Americans as both unusual and deeply disingenuous.
