After + Present Perfect tense

[michaell423]

Hi,

I m just wondering which one(s) of the below sentense make(s) more sense?

I m not sure if John will come to visit me or not AFTER I HAVE CHANGED my apartment.

I m not sure if John will come to visit me or not AFTER I CHANGED my apartment.

I m not sure if John will come to visit me or not ONCE I HAVE CHANGED my apartment.

Can after followed by present perfect tense please? I think "have done" has alreay implied the meaning of "after".

Refers to "A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is whether tourists will continue to visit game parks and see rhinoceroses after their horns are trimmed."

Thanks, Michael

I don't understand this question at all.

As to your question of what makes more sense, that is *never* the question you should be asking in SC. You should only be looking for actual mistakes, not what makes sense (or more sense).
