how to email address Apple Store iPhone 4

No idea what language you do speak, but odds are pretty high that somone in the Houston store speaks Spanish.

Why do you need to contact that store specifically?

I say in Russian, at the store I bought iPhone 4, you must receive a copy of the check to buy iPhone

Try posting in your native language what it is you wish to learn or accomplish, since you don't speak English. Then someone may be able to direct you appropriately. The Apple Stores do not normally publish email addresses via which you can contact them.

Regards.

Who can help me and call the store and ask them to send to my email a copy of the check? Or ask the representatives of the store what their email address?

No one here can or will call an Apple Store for you and Apple would not respond to a request from someone other than you for anything that would contain personal information.

What "check" do you need a copy of? Do you mean a receipt for the purchase of an iPhone you purchased in the US. If that is what you need, for what purpose do you need a receipt?
