Have you ever been to my hometown? Or, Have you ever visited my hometown. Although we understand native city or native town, we have the word hometown which is more naturally used. For example, My hometown newspaper, or my hometown mayor.

Have you ever been to [name of city], my hometown? **Always put the name of the city BEFORE you say "hometown.** It's a matter of etiquette, actually. Placing words like "hometown" in a position of importance sounds, well, needy. In fact, you're better of not even using the word.

AllenT's answers are the best. "Did you visit my native city?" does not sound friendly at all. Too direct. It would be better to say, "Have you visted my hometown?". As for your question, it is not "grammatically" correct if you mean, "Have you even been TO my hometown". This sounds friendlier. "Have you been in my homestown" is too direct a questioning. Like a police interrogating someone. These are the subtle differences.

"Have you ever visited my native city?" or "Have you ever been TO my native town?" There is really no difference in meaning between the two. Grammatically, the first construction uses the past perfect verb "visited." The second construction uses the same verb tense, but also uses the prepositional phrase "to my native town?"
