How to open an official Apple store

The required qualifications are very strict. As Antonio says, Apple corporate owns all official Apple Stores in the USA, but if you were to go forward with becoming an Apple Authorized Reseller (AAR), you would start here. Be aware you would need serious capital to do this. Or, if you want to become an Apple Authorized Service Provider (AASP), start here. It’s not necessarily any easier to become an AASP than an AAR.

As you would expect only Apple can open an 'official' Apple Store.

Perhaps you mean an Apple Authorised Reseller (VAR or PAR) and/or an Apple Authorised Repair Centre? If that's what you mean you'll have to talk to Apple to find out what their requirements are. You won't necessarily find that information here on a user-to-user discussion forum. A couple of places to start would be Apple's Contact Us link on their main webpage or going to your nearest Apple Store and asking them what's involved. They may put you in touch with someone at Apple who can assist you further?

If you do mean a reseller/repair centre store bear in mind the costs (especially the costs), time and effort required on your part to make it happen.
